Question

How do you determine if `4x^2 - 4` is an even or odd function?

Answer 1

A function `f(x)` is said to be odd if `f(-x)=-f(x)`

AND

A function `f(x)` is said to be even if `f(-x)=f(x)`

In our case the given function is `f(x)=4x^2-4)`

If we plug in `x=-x` we get

`f(-x)=4(-x)^2-4=4x^2-4=f(x)->` This means `f(x)` is EVEN
