Answer: Choice C

[tex]f(x) = -3x^2 + 4[/tex]

================================================

Explanation:

If all the exponents are even, then the polynomial function is even.

  • Choice A has a mix of even and odd exponents here, so choice A is neither even nor odd. We can rule this out.
  • Choice B is the same story as choice A. So we can rule that out as well.
  • Choice C has all of its exponents even. Therefore function C is an even function, and it's the final answer.
  • Choice D is the same story as choice A. The only difference is the leading coefficient is positive.
