A function f is defined as follows: f: Z R Which of the following statements would be true? f is onto if the range of f is the entire set of real numbers. f is onto if every integer in Z has an output value f is onto if every real number that can be output by this function, can only be output by a single value from the domain. f is onto if no integer from z has more than one output.
A function f is defined as follows: f: R R f is said to be one to one if for every real number x, there is exactly one real number y such that f(x)=y. Of is said to be one to one if every real number y can be output by f for some real number x. Of is said to be one to one if every real number y, there is exactly one real number x such that f(x)=y. f is said to be one to one if it is the only function defined that way.
A function f defined as follows: f: N→ Z is a bijection. Select all of the following that are true. f is not one to one f is one to one f is onto f is not onto
Question 6 (1 point) Select all of the functions that are bijections from the set of reals to the set of reals. f(x) = x + 1 x + 2 f(x) = x5 + 1 f(x)=-3x + 4 f(x) = -3x² + 7
Question 7 (1 point) Select all of the following functions from the set of integers to the set of integers' that are one to one. f(x) = |x| f(x) = x² + 1 f(x) = x³ f(x) = x - 1
