Question

is the function r(x) even, odd, or neither?
even
odd
neither

Explanation:

Step1: Recall symmetry rules

A function is even if its graph is symmetric about the \( y \)-axis, odd if symmetric about the origin.

Step2: Analyze the graph

The graph of \( r(x) \) is symmetric across the \( y \)-axis (left and right halves mirror over \( y \)-axis).

Answer:

even
