Question

Find the requested function value
f(x)=6x+9, g(x)=-5x^2+9x-9
Find (g o f)(7)

Answer 1

You'll have to compose the two functions.
Begin by doing the function composition between these two functions.

Answer 2

(g o f) = -5(6x+9)^2 + 9(6x+9) + 9
(g o f)(7) = -5(51)^2 + 9(51) + 9
- ill let you compute this!

Answer 3

basically its a composite function - you replace every x in g by f which is 6x+9

Answer 4

- which is my first line
- then you replace x by 7 fot calcuate (g o f) (7)
