Domain: $-oo<"x"<+oo$
Range: $g(x)>0$

From the given equation, $g(x)=5^x$ , all real values of x may be use in the equation. The domain is $(-oo, +oo)$

For the range, whether the value of x is positive or negative, there can never be a value of $g(x)$ that is 0 or lower than 0. That is $g(x)>0$

See the graph of $g(x)=5^x$

graph{y=5^x[-20,20,-10,10]}

God bless...I hope the explanation is useful.
