Jul 04, 07 · We need to determine when f(a b) = f(a) f(b) We can determine the correct answer choice by substituting numerical values for a and b We could use any two values for a and b, but for simplicity, let's choose a = 1 and b = 2 The. Conversely, assume that f(f−1(C)) = C for all C ⊆ Y but that f is not ontoThen there exists y∈ Y such that for all x∈ X, we have y6= f(x) Let C= {y} Then f−1(C) = ∅ and f(f−1(C)) = ∅ 6= C since y∈ C ContradictionHence, f is onto Thus, f is onto if and only if f(f−1(C)) = C for all C⊆ Y 8(a) Claim f(A∪B) = f(A) ∪f(B).

The two points (a,f(a) and (b,f(b)) we can write the equation of the line through these points and where it crosses the xaxis is our guess –For the equation of the line through (a,f(a)) and (b,f(b)) (using the pointslope formula) we have y −f(a) = f(b) −f(a) b−a x−a) By setting y = 0 and solving for x we get x =.

1222 (a) Prove that f(A ∩ B) = f(A) ∩ f(B) for all A,B ⊆ X iff f is injective Proof We show the implications separately =⇒ Let x 1,x 2 ∈ X be arbitrary with f(x 1) = f(x 2) Let A = {x 1} and B = {x 2} By assumption, f(A∩B) = f(A)∩f(B) = {f(x 1)}∩{f(x 2)} = {f(x 1)} This implies that there exists an element x ∈ A. As you can see, this function is split into two halves the half that comes before x = 1, and the half that goes from x = 1 to infinity Which half of the function you use depends on what the value of x is Let's examine this Given the function f (x) as defined above, evaluate the function at the following values x = –1, x = 3, and x = 1.

Jun 02, 07 · The approach I would take is to plug in ab in place of x into each function (this is f(ab)) then see if you can rearrange to get something equal to f(a)f(b) A f(ab) = (ab)^2 = a^2 2ab b^2 = f(a)f(b)2ab B f(ab) = a b 1 = f(b) a C f(ab) = sqrt(ab) not equal f(a)f(b) = sqrt(a)sqrt(b).

Then add the square of x to both sides of the equation This step makes the left hand side of the equation a perfect square b^{2}2xbx^{2}=a^{2} Add \left(xa\right)\left(xa\right) to x^{2} \left(bx\right)^{2}=a^{2} Factor b^{2}2xbx^{2} In general, when x^{2}bxc is a perfect square, it can always be factored as \left(x\frac{b}{2.

In mathematical analysis, the intermediate value theorem states that if f is a continuous function whose domain contains the interval a, b, then it takes on any given value between f(a) and f(b) at some point within the interval This has two important corollaries If a continuous function has values of opposite sign inside an interval, then it has a root in that interval (Bolzano's theorem). Derivative examples Example #1 f (x) = x 3 5x 2 x8 f ' (x) = 3x 2 2⋅5x10 = 3x 2 10x1 Example #2 f (x) = sin(3x 2) When applying the chain rule f ' (x) = cos(3x 2) ⋅ 3x 2' = cos(3x 2) ⋅ 6x Second derivative test When the first derivative of a function is zero at point x 0 f '(x 0) = 0 Then the second derivative at point x 0, f''(x 0), can indicate the type of that point.

F(x) hasa value equal to f(c) = ∫b a f(x)dx b a Multiplying bothsides by b a proves the result 4The first fundamental theorem of integral calculus We are now in a position to prove our first major result about the definite integral The result concerns the socalled area function F(x) = ∫ x a f(t)dt and its derivative with respect to x. F(a) = f(b) ⇒ (a4,a−1) = (b4,b−1) ⇒ a4 = b4 and a−1 = b−1 ⇒ a = b and a = b ⇒ a = b Therefore f is onetoone • ONTO COUNTEREXAMPLE There is no way to get to (3,3) since that would require that x 4 = 3 and x − 1 = 3 which would mean that x = −1 and x = 4 at the same time which is impossible. Jul 04, 12 · $\begingroup$ Think of f(abx), what happens to f(abx) at x=a, it is f(aba)=f(b) and what happens as x goes from 'a' to 'b', evaluate f(abx) at x=b, it becomes f(abx)=f(abb)=f(b) Therefore you are integrating a function f(abx) which takes values f(b) to f(a) as x goes from 'a' to 'b'The image below isn't accurate in the sense that as you integrate the function f(abx.

If f′(x) < 0 for all x ∈(a,b), then f is decreasing on (a,b) First derivative test Suppose c is a critical number of a continuous function f, then Defn f is concave down if the graph of f lies below the tangent lines to f Defn f is concave up if the graph of f. F(b)¡f(a) b¡a = 0 On the other hand, f0(x) = 5x4 10, and since x4 ‚ 0 for all x, we conclude that f0(x) ‚ 10 for all x This contradicts the existence of a number c for which f0(c) = 0, so we must conclude that there are not two distinct roots Thus there is at most one solution to the given equation 2 Show that the equation cosx = 2x.

Sep 30, 17 · Answer is (ab)/2 int_a^b f(x) dx Let "I" be the integral, I = int_a^b xf(x) dx (1) Using the property of definite integrals, I = int_a^b (abx) f(abx) dx It is given that, f (abx) = f(x) implies I = int_a^b (abx) f(x) dx implies I = (ab) int_a^bf(x) dx int_a^b x f(x) dx. In addition to linear, quadratic, rational, and radical functions, there are exponential functions Exponential functions have the form f(x) = b x, where b > 0 and b ≠ 1 Just as in any exponential expression, b is called the base and x is called the exponent An example of an exponential function is the growth of bacteria.

If f X → Y is injective and A is a subset of X, then f −1 (f(A)) = A Thus, A can be recovered from its image f(A) If f X → Y is injective and A and B are both subsets of X, then f(A ∩ B) = f(A) ∩ f(B) Every function h W → Y can be decomposed as h = f ∘ g for a suitable injection f and surjection g.

Nov 16, 13 · It follows that x∈A ∧ x∉B, hence y∈f(A) ∧ y∉f(B) ⇒ y∈f(A)∖f(B) Therefore f(A∖B) ⊆ f(A)∖f(B) Note we really did need the injectivity of f here if there were an x'∈B such that y=f(x'), then still y∈f(A∖B), but y∉f(A)∖f(B) We now conclude that f(A)∖f(B) = f(A∖B). F(x) on a,b Let P 2(x) be the quadratic polynomial that interpolates f(x) at a,c= ab 2 and b I(f) ≈ Z b a P 2(x)dx (65) = Z b a (x−c)(x−b) (a−c)(a−b) f(a) (x−a)(x−b) (c−a)(c−b) f(c) (x−a)(x−c) (b−a)(b−c) f(b) dx This can be evaluated directly But it is easier with a change of variables Let h= b−a 2 and u= x.

I love this formula For being so useful, it is surprising that it was not discovered until the th century!.

As the function f(x) is polynomial function that means it must be continuous And zeros of function is its roots Now There are two possibilities f(a) > 0 and f(b) < 0 Or f(a) < 0 and f(b) > 0 We'll take second case If the function is having N.
