Question

. When f(x)=6x + 4 and g(x) = -6x + 3, find (g ◦ f)(6).

Answer 1

- 237

Explanation:

To evaluate (g ￮ f)(6) , evaluate f(6) and use the value obtained to evaluate g(x), that is

f(6) = 6(6) + 4 = 36 + 4 = 40, then

g(40) = - 6(40) + 3 = - 240 + 3 = - 237

Answer 2

First find g o f(x)

= -6(6x +4) + 3

= -36x -24 +3

= -36x -21

g o f(6) = -36(6) - 21

= -216-21

= -237

Hope this helps.
