Answer 3

first find g(5)

Answer 4

5x^2 - 5?

Answer 5

almost, try one more time

g(x) = x^2 - 1
g(5) = ?

Answer 6

I don't multiply the power by 5, do I?

Answer 7

I'm sorry, I'm a history and literature guy, math is not my forte.

Answer 8

no need to apologize

g(x) = x^2 - 1
g(5) just means replace "x" with 5

Answer 9

Oh, so 5^2 - 1 = 24?

Answer 10

great! g(5) = 24

f(g(5)) = f(24) = __?

Answer 11

5*24 = 120?

Answer 12

uh, not quite

f(x) = 3x - 2
f(24) = ?

Answer 13

3*24 - 2 = 70

Answer 14

excellent! that's our final answer
