    Since x^2 is always>0 then so is X^2+1. However since x can also equal zero from the domain, the range becomes g(x)>or equal to 1.

    For g:

    The domain is any real x. Well you know the smallest value of g is 1 meaning that the range is g(x)>=1.

    For f:

    You know the domain is x>=0

    You know therefore the smallest value is e^0 = 1.

    So f(x) >=1.
