Question

How do you determine if `f(x) = 1` is an even or odd function?

Answer 1

`f(x)=1` is even function.

Explanation:

A function `f(x)` is even if `f(-x)=f(x)` and

f(x)`is odd if`f(-x)=-f(x)#

If `f(x)=k`, where `k` is a constant,

then obviously `f(-x)=f(x)` and `f(x)` is even function.

Hence, `f(x)=1` is even.
