Please help me ......:(

Answer 1

Answer: B) F(x) = √x and G(x) = 3x + 2

Explanation:

The composite function G(F(x)) is when you replace every x-value in the G(x) function with the F(x) function.

`A)\ G(3x+2) = √(3x+2)\\\\B)\ G(√(x))=3(√(x))+2\quad =3√(x)+2\\\\C)\ G(√(x)+2) = 3\quad \text{there are no x-values in the G(x) function to replace}\\\\D) G(3√(x))=2\quad \text{there are no x-values in the G(x) function to replace}`

The only one that matches G(F(x)) = 3√x + 2 is OPTION B
