Thread: Help please x-intercepts

Hi,
I don't understnad how t solve this question. Can somebody help me? THank you.
P(x) is an even function and has x-intercepts at x = 2 and x = 3. What other values are also guaranteed to be x-intercepts?

Hello, cuteisa89!

P(x) is an even function and has x-intercepts at x = 2 and x = 3.
What other values are also guaranteed to be x-intercepts?

Since P(x) is an even function, it is symmetric to the y-axis.

So there must be x-intercepts at -2 and -3, too.
