Answer:i think 8x-4 is 4x.

Step-by-step explanation:

9 is in the domain of f (g (x))

Step-by-step explanation:

f (g (x)) = - 8*g (x) - 4

= - 8 * (7x+3) - 4

= - 56x - 24 - 4

= - 56x - 28

= - 28 (2x + 1)

f (g (9)) = - 28 (2*9 + 1)

= - 28*19

= - 532

Since 9 can be plugged into the compound function, it is in the domain.
