Question 296771: Problem: Determine whether f(x)=3x^4-5x^2+2 is even, odd, or neither.
.
.
I automatically want to say "neither" because of that 3x to the fourth power, but I tried plugging "-x" in the equation in place of "x" just to test it.
f(-x)=3(-x)^4-5(-x)^2+2.
.
My problem is, I don't understand what I'm looking at or why. Should I plug a real number in to test it or what? Any explanation is helpful (especially if I'm doing this wrong!!!) Thanks :)
