Question

Help !!?!?!?!?!?!
Given the following functions f(x) and g(x), solve f[g(6)] and select the correct answer below:
f(x) = 6x + 12
g(x) = x − 8

A) −96
B)0
C)24
D)48

Answer 1

You need to first substitute 6 for x in the g(x) equation
What would that get you?

Answer 2

g(x)=2

Answer 3

no it would be -2

Answer 4

because 6-8=-2

Answer 5

then plug -2 into the f equation

Answer 6

ok so f(x) = 6-2 + 12 =f(x)=16

Answer 7

incorrect

Answer 8

wait f(x)=0?

Answer 9

6(-2)+12
-12+12=0

therefore

f(g(x))=0

because you plug x into the g(x) equation first then your g(x)= -2 so then you plug -2 into the f(x) then that gives you your final answer
