Answer: f(f(f(x)))=8x-7

Step-by-step explanation:

Since we were given f(x) and f(f(x)), We plug that into f(x) again to get f(f(f(x))).

Answer:

The slope of the line is -3.

Step-by-step explanation:

m= -3-6/2+1 (remember that a negative minus a negative gives you a positive)

Which equals:

m=-9/3

Divide and you get -3.
