Question

If f(x) = -6x + 5 and g(x) = x+1, what is (fºg)(3)?

Answer 1

Answer:

(f o g)(3) = -19

Step-by-step explanation:

(f o g)(3) is f(g(3)).  You need to first find g(3).

g(x) = x + 1

g(3) = 3 + 1

g(3) = 4

Next, you need to find f(g(3)).  Since, g(3) = 4, you are finding f(4).

f(x) = -6x + 5

f(4) = -6(4) + 5

f(4) = -24 + 5

f(4) = -19

(f o g)(3) = -19
