If f of x equal to one half x minus six and g of x equal to one half x plus seven, find the sum of f(x) and g(x) .
 
f(x) + g(x) = x + 1
 
If f of x equal to one half x minus six and g of x equal to one half x plus seven, find the difference of f(x) and g(x).
 
f(x) – g(x) = –13
 
If f of x equal to one half x minus six and g of x equal to one half x plus seven, find f of g.
 
f of g equal to one fourth x minus five halves
 
If f of x equal to one half x minus six and g of x equal to one half x plus seven, find g of f.
 
g of f equal to one forth x plus four
