If f (x) = -4x+2 and g (x) = radical over x-8, what is (f g) (12)

(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.
