Let f(x) = x2 + 6 and g(x) = x + 8x g ( x ) = x + 8/ x . find ( g o f)(­ -7)

question 17 options: 63 /55 295 /49 384/ 7 -57/ 7

63/55

Step-by-step explanation:

Assuming and . Find  ( g o f)(­ -7) by substituting f into g. Then -7 into the new expression.

( g o f)(­ -7) =

y/x=18

step-by-step explanation:

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
