Question

Determine whether the function f(x) = 3x is even or odd.

The function is even because f(-x) = f(x).
The function is odd because f(-x) = f(x).
The function is even because f(-x) = -f(x).
The function is odd because f(-x) = -f(x).

Answer 1

A. f(-x) = f(x)

Explanation:

When plugged into a graph, we can see that the y value of -x is equal to x.

This means, that if we compare the y value of x=3 and x=-3, they will be the same on the graph.
