Question

What are odd functions?

Answer 1

`f(x)` is an odd function if `f(-x) = -f(x)`

Explanation:

The answer above defines an odd function.

An example: `f(x) = x^3` is an odd function because:

`f(-x) = -x^3 = -f(x)`

NB: An even function is one that satisfies:

`f(-x) = f(x)`

`f(x) = x^2` is an even function.
