Answer:

To find the value of f(g)(-2), we need to substitute the value of -2 into the function g(x) and then use the result as the input for the function f(x).

First, let's evaluate g(-2):

g(x) = 5x + 4

g(-2) = 5(-2) + 4

= -10 + 4

= -6

Now that we have the value of g(-2) as -6, we can substitute it into the function f(x):

f(x) = 8 - 10x

f(g(-2)) = 8 - 10(-6)

= 8 + 60

= 68

Therefore, the value of f(g)(-2) is 68.
