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

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

                                We have the following funtion:

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

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

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
