Answer:
zero or 0
Step-by-step explanation:
Given the functions in the question
f(x) = 6x + 12
g(x) = x − 8
We need to calculate
f[g(6)]
First calculate the inner function
g(6) = x − 8
g(6) = 6 − 8
= -2
Now calculate the Second / outer function by inputing the answer from first calculation
f(-2) = 6x + 12
f(-2) = 6x + 12
= 6(-2) + 12
= -12 + 12
= 0
Therefore, the value of f[g(6)] is 0.
