Question

F(x)=3x+(5/x) what is f(a+2)

Answer 1

Explanation

`f(x)=3x+(5)/(x)`
`f(a+2)=6+3a+(5)/(a+2)`

Step 1

replace (a+2) in the place for x

then,

`\begin{gathered} f(x)=3x+(5)/(x) \\ f(a+2)=3(a+2)+(5)/((a+2)) \\ f(a+2)=3a+6+(5)/(a+2) \\ f(a+2)=6+3a+(5)/(a+2) \\ \end{gathered}`

I hope this helps you.
