Find the domain of the function. sqrt(x-7)/2x+5. Write your answer as an interval or union of intervals.
---------------------------------------
sqrt(x-7)/(2x+5)
----
The denominator cannot be zero
and the radicand cannot be negative.
---------------------------------------
x cannot be -5/2 and x-7 must be >=0, so x >= 7
----
Domain: [7,+oo)
