Answer:
The correct answer is 1
Step-by-step explanation:
The composite function g(f(x)) will be given by;
(1+x)^2 -(1+x)
Substituting x with zero yields g(f(0)) =0.
On the other hand, the composite function f(g(t)) will be given by;
1+t^2-t
Substituting t with zero yields f(g(0)) =1
Finally, g(f(0)) + f(g(0)) =0+1 = 1.
