Hi, there--

Problem:
Find g(a+1) when g(x) = 1/2x -5 . 


I think you found g(a) instead of g(a+1).

Answer:
I'm not sure from your typing whether you mean
I: g(x) = 

OR

II: g(x) = 

OPTION I:
g(x) = 

Substitute a+1 for x in the function g. Watch those parentheses!
g(a+1) = 

Simplify.
g(a+1) = 
g(a+1) =  
 
OPTION II:
g(x) = 

Substitute a+1 for x in the function g. 
g(a+1) = 

Simplify.
g(+1) = 

There you go!
