Given the functions below find fg2 I know how to find the fg

Given the functions below, find (f+g)(2)

I know how to find the f+g, but I dont understand what to do with the (2) in the equation.

here after finding (f+g) we have to substitute x by 2

f(x) =4x^2 +2x

g(x) =5x -4

(f+g) =(4x^2 +2x)+(5x-4)

(f+g) =4x^2 +7x -4

(f+g)(2) =4(2)^2 +7(2) -4

(f+g)(2) =16+14-4

(f+g)(2) =26

Thank you
