Question

How do you determine if `absx` is an even or odd function?

Answer 1

`abs(x)` is an even function.

Explanation:

A function `f(x)` is even if `f(-x) = f(x)` for all `x` in its domain.

A function `f(x)` is odd if `f(-x) = -f(x)` for all `x` in its domain.

In our example, we have:

`abs(-x) = abs(x)`

for any value of `x`.

So `abs(x)` is an even function.
