Find G(4)
G(x) = 2x - 6
G(4) = 2

Find x when F(x) = 2
F(x) = 3x - 7
x = 3
100
Find F(G(2))
F(x) = 2x + 1
G(x) = 3x - 4
F(G(2)) = 5
100
Yes

Find P(2)
J(x) = 6x + 5 and P(x) = 7x - 1
P(2) = 13

Find x when G(x) = 4
F(x) = 2x + 1 and G(x) = 2x - 6
x = 5

Find F(G(H(2)))
F(x) = 3x - 1
G(x) = x^2
H(x) = 5x - 5
F(G(H)))= 74

Write the following answer as a point:
Find g(6)
G(x) = x^2 - 6
G(6) = (6,30)

Find x when H(x) = 8
H(x) = x^2 - 1
x = 3 or -3

Find M(N(1)) + M(5)
M(x) = 2x - 2
N(x) = x^2 + 5
M(N(1)) + M(5) = 18

Is this a function? WHY??
No. The 1's have different outputs.
