$f (x + 2) = 3 x + 10$ $f(x+2)=3x+10$

$f (x + 2)$ $f(x+2) " "$ means replace all the $x s$ $" "xs" "$ with $(x + 2)$ $" "(x+2)$

$f (x) = 3 x + 4$ $f(x)=3x+4$

$f (x + 2) = 3 (x + 2) + 4$ $f(x+2)=3(x+2)+4$

Now simplify

$f (x + 2) = 3 x + 6 + 4$ $f(x+2)=3x+6+4$

$f (x + 2) = 3 x + 10$ $f(x+2)=3x+10$

If f(x)=3x+4f ( x ) = 3x + 4, what is f (x +2)?
