Complete.

1.   f(x) = 14x + 13
g(x) = -11x2 + 13x + 15

find f(f(4))
2.   f(x) = -12x2 - 10x + 15
g(x) = -10x2 - 13x + 13

find g(f(6))
3.   f(x) = 12x2 - 11x - 10
g(x) = 14x - 13

find g(g(5))
4.   f(x) = -14x2 + 14x - 11
g(x) = 13x2 + 13x + 12

find f(6) ÷ g(6)
5.   f(x) = -10x3 + 10x2 + 14x + 12
g(x) = 15x3 + 15x2 - 14x + 14

find g(-1) × g(-9) + g(12) × f(3)
6.   f(x) = 13x3 + 15x2 - 10x + 12
g(x) = 13x + 15

find f(6)-g(6)
7.   f(x) = -14x - 12
g(x) = -13x - 11

find g(-9) × g(-11) - f(-3) × f(-7)
8.   f(x) = 10x + 14
g(x) = -11x - 12

find g(g(9))
9.   f(x) = -12x2 + 11x - 13
g(x) = 15x - 12

find f(f(8))
10.   f(x) = 10x3 + 10x2 + 11x - 14
g(x) = -14x + 12

find g(f(6))
11.   f(x) = -10x + 13
g(x) = -15x - 15

find g(-7) × g(10) - f(8) × f(3)
12.   f(x) = 10x + 12
g(x) = -10x2 + 15x - 10

find f(-3) × g(-5) + g(9) × f(1)
13.   f(x) = -10x3 + 13x2 - 12x - 11
g(x) = 14x2 - 15x - 14

find f(15) ÷ g(15)
14.   f(x) = 15x2 + 11x - 10
g(x) = -13x + 10

find f(5)-g(5)
15.   f(x) = -15x + 12
g(x) = 12x2 + 12x + 15

find f(3)-g(3)
