Question

Help me determine if this function is even or odd!

Answer 1

If u end up with the exact same function that you started with (that is, if f (−x) = f (x), so all of the signs are the same), then the function is even if u end up with the exact opposite of what you started with (that is, if f (−x) = −f (x), so all of the signs are switched) then the function is odd

Answer 2

Even - because the function is symmetric across the y-axis.

Explanation:

An even function is symmetric across the y-axis of a graph. An odd function is symmetric across the origin of a graph.

I graphed the function and you can see that is in symmetric across the y-axis. Therefore, it is even.
