Use the following functions to answer the questions below: $$\begin{aligned} f(x) \amp= \ln(x)\\ g(x) \amp= \log_{10}(x)\\ h(x) \amp= \ln(x-10)\\ j(x) \amp= \ln(x)+10 \end{aligned}$$ The set of all real numbers is the domain of which function(s)? Answer: ? only f only g only h f and g f and h g and j f, g and h f, g and j all of these none of these The set of numbers greater than zero is the domain of which function(s)? Answer: ? only f only g only h f and g f and h g and j f, g and h f, g and j all of these none of these Is $x=10$ in the domain of the function $h\text{?}$ Answer: ? yes no
