Question 791770: I dont know how to get these? I only know f(x) 's? help me please!

f(x) = 15x - 12
g(x) = -15x2 + 14x - 10
find g(g(7))
A -6288203
B6543
C639
D-4595
E 538
F -162,632

. f(x) = -13x2 + 12x + 14 g(x) = 11x - 13
find f(g(7))
A -162,632
B-6288203
C639
D-4595
E 538
F -52466

f(x) = 11x + 15
g(x) = -11x3 - 15x2 + 13x - 13
find g(f(6))
A -4595
B-52466
C-6288203
D-5943226
E 639
F 538
