Step-by-step explanation:
Answer: 336
Step-by-step explanation:
The numbers are all multiples of 6
63x+45x = 108x
You just multiply 3x by 21 and 15 to get 63x and 45x. You then add the like terms to get 108x.
The asymptote for f(x) is y = 0
Notice the asymptote for g(x) is y = -1, which shift f(x) down 1
apply this to f(x)'s rule: 
Notice the graph of f(x) is shifted right 2 units...this horizontal movement must be applied to the x in f(x)'s rule:
