Answer:

6x+20

Step-by-step explanation:

F(x) = 6x+2

f(x+3) means replace x with x+3

F(x+3) = 6(x+3)+2

= 6x+18+2

= 6x+20

Answer:

A; F(x+3) = 6x^2 + 20x + 6

Step-by-step explanation:

To find it you just would multiply F(x) onto the other side. So it would look like this:

F(x+3) = 6x + 2 (x+3)

F(x+3) = 6x^2 + 2x + 18x + 6 *combine like terms getting you

F(x+3) = 6x^2 + 20x + 6

Hope this helped!!
