Question

If f(x) = 3x+5/x , what is f(a+2)?

Answer 1

Hi!!!

The Answer is : C

✍️ Solution:

--------------------------------------------------------------------------------------------------------------

We have the following funtion:

`f(x)= \mathrm{3x+(5)/(x) }`

when the variable "x" is equal a (a+2)

`f(x=(a+2))=\mathrm{3(x=(a+2))+(5)/((x=(a+2))) }`

`f(a+2)=\mathrm{3(a+2)+(5)/((a+2)) }`
