SOLUTION: Calculate the indicated value. Remember to show your work. (7) f(x) = 7x - 27x^2 - 7; Find f(-7) (8) f(x) = -8x -5x^2 + 6; Find f(-10)

Question 1198109: Calculate the indicated value. Remember to show your work.
(7) f(x) = 7x - 27x^2 - 7; Find f(-7)

(8) f(x) = -8x -5x^2 + 6; Find f(-10)

(9) f(x) = 11x^2 + 12x - 12; g(x) = 12x^2 - 11x + 11; Find g(f(3))

(10) f(x) = 13x - 10; g(x) = -12x^3 + 11x^2 - 12x - 11; Find f(g(3))

(11) f(x) = 14x^2 + 15x - 14; g(x) = 14x^2 + 11x - 10; Find f(f(4))

f(x) = 7x - 27x^2 - 7; Find f(-7)
-------------
Sub -7 for x
---
f(7) = 7*(-7) - 27*(-7)^2 - 7
Multiply and add.
