Question

Find (g*f)(3)
f(x)= 3x-2
g(x)=x2

Answer 1

49 choice C is the correct solution

Explanation:

The composite function, (g o f) simply means we substitute the function f(x) in place of x in the function g(x). since g(x) =x^2, (g o f) =(f(x))^2 = (3x-2)^2. The final step is to substitute x=3 in this expression which yields 49

Answer 2

C

Explanation:

( g o f)(­ 3) means to substitute the value x=3 after substituting f(x) into g(x).

`(3x-2)^2\\(3(3)-2)^2\\(9-2)^2\\7^2\\49`
