Question

Which statement is true about function f, which is shown in the graph?
f(x)=x^6+10x^4-11x^2

Answer 1

The correct answer is The function is even.

To do this, you take the function and plug –x in for x, and then simplify. If you 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.
