(10 points) Define a function on a set of real numbers by the rule f(x) = 2 Is ſ a one-to-one correspondence (bijective)? If so find its inverse. Formally justify your answer.
how do u do 6? F-'(C-D)= F-'(C)-F-'(D). 4. (10 points) In following questions a function f is defined on a set of real numbers. Determine whether or not f is one-to-one and justify your answers. (a) f(x) = **!, for all real numbers x #0 (6) f(x) = x, for all real numbers x (c) f(x) = 3x=!, for all real numbers x 70 (d) f(x) = **, for all real numbers x 1 (e) f(x) = for all real...
x+3 2x Define f(x) for all real numbers x = 0. Is f a one-to-one function? Prove or give a counterexample. (Note that the write-up of the proof or counterexample should only have a few of sentences.) If the co-domain is all real numbers not equal to 1, is f an onto function? Why or why not? (Note this problem does not require a full proof or formal counterexample, just an explanation.)

A function f : A - B is said to be injective (or one-to-one) provided Va, a2 € A, f(a) = f(az) ► a1 = . A function g: A + B is said to be surjective (or onto) provided W6 € B, 3 some a € A such that g(a) = b. A function h: A → B is said to be bijective (or a bijection or a one-to-one correspondence) if it is both injective and surjective. The following...

Explain. 5. Repeat question 4 for the function...
For the problems below each function is one-to-one on the specified domain x. By letting y = range of f, we have a bijection from X to Y. Find the inverse of each function. f(x) = 5^x, X = set of real numbers f(x) = 5 + 2/x, X set of nonzero real numbers
