Question

Consider the two function machines that are placed as shown. Find the final output for 0,5,12.

f(x)=8x

g(x)=x+3

(g°f)(x)

The output for 0 is...
The output for 5 is...
The output for 12 is...

Answer 1

f(x)=8x, g(x)=x+3

(g°f)(x) = g(f(x)) = g(8x) = 8x + 3

(g°f)(0) = 8×0 + 3 = 3
(g°f)(5) = 8×5 + 3 = 43
(g°f)(12) = 8×12 + 3 = 99

Answer 2

Answer:

g(x) = x+6

g(60) = 66........
