Answer:
(f g(12)) is = -6
Step-by-step explanation:
Given functions are
f(x)= -4x+2 and g(x)= radical over x-8
Now, by putting g(x) in f(x), the function will be
f(x)= -4 √(x-8)+2.
Now, putting 12 in place of x,
√12-8= √4= 2. Here the answer is positive. That's why it will have a result. If it was negative it wouldn’t have answer and would have called indeterminate form.
So, -4 X 2+2 = -8 +2 = -6.
So the answer is -6.
