**Reiny**, Tuesday, May 6, 2008 at 3:55pmThe reason you have received no reply so far is because the way you typed your function is confusing.

You have 3 equal signs in the same line, is that what you wanted?

is your function f(x) = x^{3}?

if you simply want f(-2) and f(2) that would be easy

f(-2) = (-2)^3 - 7(-2)

= 6

f(2) = 2^3 - 7(2)

= -6
