Question 347046
Find the domain of the given function: 
h(x)=1/x+9 
Type your answer in interval notation



h(x) = 1/x + 9
the domain is all real numbers x can be so that the function h(x) is also real
x is the denominator in 1/x
you can not divide by 0
x <> 0
(-infinity,0)U(0,infinity)  --> U means union, notice no square brackets, end points excluded
