Need help with with a,b,c,d,e,f has to due with fog.

Evaluate each expression using the values given in the table. x -3 -2 -1 0 1 2 3 f(x) -4 -3 -2 -1 2 3 4 g(x) 7 3 0 -1 0 3 7 a-(fog)(1} b-(f09)(-1} C-(Qof)(-1) d-(g of)(0) 9- (99)(-2) f- (fof)(-1) a.(fog)(1)=D b.(fog)(1)=D c.(gon(1)=D d.(gon(0)=D e.(gog)(-2)=D f.(fof}(-1)=D
