If f(x)=x^2-1 and g(x)=x+2 then g(f(x)=

Step-by-step explanation:

Just plug the f(x) function into x for g(x).  Then solve.

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

Step-by-step explanation:

If f(x)=x^2-1 and g(x)=x+2 then g(f(x))= g(x²-1) = (x²-1)+2= x²+1

what level of math? also i don't need to be paid if i can you.
