Question

The function f(x) represents the time it takes a commuter to travel in the morning to work. The function g(x) represents the time it takes a commuter to travel in the evening from work. Given f(x) = 5x − 7 and g(x) = 11x − 1, solve for (f + g)(x) to determine the total roundtrip time.

Answer 1

Its C-(F+G)(x)=16x-8 got it right on the flvs test!

Explanation:

Answer 2

`\left(f\:+\:g\right)\left(x\right)\:=\:16x-8`

Explanation:

Given

`f(x) = 5x-7`

and

`g(x) = 11x -1`

As the formula

`(f + g)(x) = f (x) + g(x)`

`=\left[5x\:-\:7\right]\:+\:\left[11x\:-1\right]`

`=5x-7+11x-1`

`=5x+11x-7-1`

`=16x-7-1`

`=16x-8`

Therefore,

`\left(f\:+\:g\right)\left(x\right)\:=\:16x-8`
