1

6

5

−1

Answer 1

\[f(3)=3+2\]

Answer 2

yeah its 5

Answer 3

just plug it in. f(x), the x value just means the variable you will use each time x pops up in the equation, so you plug it in. in this case, your equation says f(x)=x+2, so you plug 2 in and you have f(3)=3+ 2. So your answer will be 5. just remember, plug it in!
