Answer:

  • f(g(x)) =  - 10x - 13

Step-by-step explanation:

Given functions:

  • f(x) = 5x +7

and

  • g(x) = -2x - 4

Work out the composite f(g(x)):

  • f(g(x)) = f( -2x - 4) = 5( - 2x - 4) + 7 = -10x - 20 + 7 = - 10x - 13

Answer:

f(g(x)) = -10x - 13

???? = - 8x - 13

Step-by-step explanation:

f(x) = 5x +7

and

g(x) = -2x - 4

f(g(x)) = f(-2x - 4) = 5(-2x - 4) + 7

f(g(x)) = -10x - 20 + 7

f(g(x)) = -10x - 13

f(g(x)) = -2x - 8x - 13
