Select the correct answer from each drop-down menu.

Using the classification for even and odd functions, it is found that the function is even, because f(-x) = f(x).

<h3>How we verify if the function is even, odd, or neither?</h3>

  • If for all values of x, f(x) = f(-x), the function is even.
  • If for all values of x, f(-x) = -f(x), the function is odd.
  • If neither of these statements are true, the function is neither even nor odd.

Graphing the function f(x) = 3x^4 - 5x^2, for every value of x, f(x) = -f(x), that is, the function is symmetric over the y-axis, hence it is even.
