Answer:
(f ○ g)(x) = 
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
(f ○ g)(x)
= f(g(x))
= f(x + 1)
= 
(2x+3y)+(7x-3y)
First, group like terms together, so (2x+7x) + (3y-3y). Then simplify within the parentheses. 2x+7x = 9x and 3y-3y = 0, so you have 9x, which cannot be simplified any further. The answer is 9x.
