Let the function f R R be given by 1,)- f 1 z-1 Draw the graph of f versus the values of z. Is f ...
A. (Leftovers from the Proof of the Pigeonhole Principle). As before, let A and B be finite sets with A! 〉 BI 〉 0 and let f : A → B be any function Given a A. let C-A-Va) and let D-B-{ f(a)} PaRT A1. Define g: C -> D by f(x)-g(x). Briefly, if g is not injective, then explain why f is not injective either. Let j : B → { 1, 2, 3, . . . , BI}...
(8) Given a C1-function f : Rn->M, let M (x, z) E R#x R | z- f(x)) be the graph of f. Let TpM denote the tangent space to M at a point p = (xo, 20) E M. Find TİM and compute its dimension. Hint: draw a picture.
Let f : Z * Z -> Z be given by f(a, b) = a + b - ab: Is f associative? If your answer is yes, give a proof. If your answer is no, nd a counterexample.
Area accumulation functions an introduction Given a function f(r), we create a new function F) by evaluating how much area is accumalated under f(x) 1. Example (a) Define F(f(t) dt. Evaluate the following: F(0) = F(2) F(-1) (b) Shade in and find the area represented by F(3) - F(1). (c) Find a formula for F(r) between0 and 1 (d) Give two values at which Fr)-0. (Hint: assume the graph continues to the right.) (e) Which is larger: F(3) or F(4)?...
1. (a) (6 points) Let f : A + B and g:B + C be two functions. Suppose that the composition of functions go f is a bijection. Prove that the function f : A + B must be one-to-one and that the function g:B + C must be onto. (b) (4 points) Give an example of a pair of functions, f and g, such that the composition gof is a bijection, but f is not onto and g is...
3. Consider the following piecewise function (a) Draw an accurate graph of f(). (b) As always, f(x), has an infinite number of antiderivatives. Consider an antiderivative F(r). Let us assume that F(r) is continuous (we don't usually have to specify this, but you will see in the bonus part of the question why we do in this case). Let us further assume that F(2) 1.

1. Show that f : (R,Te) → (R,Tj.), given by f(x)-z?, is a continuous bijection whose inverse function is not continuous. Here Tee and Tie are the countable complement and finite complement topologies respectively

Question 1: Let R be the set of real numbers and let 2R be the set of all subsets of the real numbers. Prove that 2 cannot be in one-to-one correspondence with R. Proof: Suppose 2 is in one-to-one correspondence with R. Then by definition of one- to-one correspondence there is a 1-to-1 and onto function B:R 2. Therefore, for each x in R, ?(x) is a function from R to {0, 1]. Moreover, since ? is onto, for every...
