What makes a function an even function? We will be using f(x) = x^2 as an example function.

Question

Keep the answer simple, 2 short sentences.

Answer 1

A function is considered even if it satisfies the condition \( f(-x) = f(x) \) for all values of \( x \). For example, in the case of \( f(x) = x^2 \), we see that \( f(-x) = (-x)^2 = x^2 = f(x) \), confirming it is an even function.
