Answer explanation

Because the limit as x approaches 2 of g(x) does not exist (the left approaches -inf while the right approaches +inf) then the composite function cannot exist.

• DNE

Answer explanation

Remember that the limit is the value that the function is approaching, so the limit of h(x) as x approaches 0 is zero. and f(0) = -1
