find the domain of f(x)=(16x+3)/(x^2+6x-72)
===================================
The domain is all values of x for which the function is defined.
The function will be defined for all values in which the denominator does not equal 0.
The denominator can be factored as
(x^2+6x-72) = (x-6)(x+12)
So the domain is all real numbers except x=6, x=-12
