Question 985455

Can someone explain this to me and how to approach it?

Which of the following functions satisfies the inequality 
f(2)is less than f(-2)?

Answer choices:
A. f(x) = 2x^2 + 2
B. f(x) = 2x^2 - 2
C. f(x) = -2x^2 - 2
D. f(x) = 2x + 2
E. f(x) = -2x-2

Thank you.

<pre>{{{highlight_green(CHOICE_E)}}} as f(2) = - 6, and f(- 2) = 2, so f(2) < f(- 2)
