Suppose f(x) is a function such that if p < q, f(p) < f(q). Which statement best describes f(x)?
a. f(x) can be odd or even.
b. f(x) can be odd but cannot be even.
c. f(x) can be even but cannot be odd.
d. f(x) cannot be odd or even.

f(x) can be odd or even.

Step-by-step explanation:

let's take two functions y(x) = sin(x) odd. and y(x) =

both functions are odd and even respectivaly both meet the constraints established in the problem.

by graphing and visully inspecting it can be verified.
