Answer by longjonsilver(2297)   (Show Source):
You can put this solution on YOUR website! Please read my Lesson on this site on functions, it will help you.
Anyway, f(x) = (1/2)x + 2
this says...whatever the value is, here it is written as "x", in the f(x) bit, then what you do is multiply it by (1/2) and then add 2...the equation!
so f(-6) = (1/2)(-6) + 2 which becomes
f(-6) = -3 + 2
f(-6) = -1
