Answer:
37
Step-by-step explanation:
(f - g)(x) is the same as
f(x) - g(x)
f(-4) - g(-4)
{ -(-4) + 8 } - { 8(-4) + 7 }
4 + 8 - { -32 + 7}
12 - ( -25 )
12 + 25
37
BTW, you can add, subtract, multiply and divide functions
(f - g)(x) = f(x) - g(x)
(f + g)(x) = f(x) + g(x)
(f * g)(x) = f(x) * g(x)
(f/g)(x) = f(x) ÷ g(x), as long as g(x) ≠ 0 (That would be undefined.)
Hope this is brainly. :)
