The table didn't turn out very good so here it is another way:
x: 2, 3, 4, 5
f(x): 5, 7, 9, 11
g(x): 0, 1, 2, 3
Answered by drwls
g(x) = x-2
g(4) = 2
g(g(4)) = 0

They have already provided you with four points on the g(x) curve. Ignore the data on f(x).
Answered by bobpursley
Notice f(x) and g(x) increase by two, and one, for each increase in x.

f(x)=2x+1
g(x)=x-2

Will that do it?
