Question 104881: I am having a hard time with functions, I need help on setting them up.
Given f(x) = –x3power – x2power + 2x – 8, find f(–1), f(0), and f(2)
Given f(x) = –5x – 1, find f(a – 1)
Given f(x) = –2x – 4, find f(–3)
Thanks so much, I am stressing out over this math.

Simply replace the x in each equation with the given value. For example: f(x) = -x^3 - x^2 +2x -8
becomes f(-1) = -(-1)^3 - (-1)^2 + 2(-1) -8 = 1-1+-2- 8 = -12. Do the same for each value f(0) and f(2). Also f(a-1) = -5(a-1) - 1....
