The function h is defined below

Question

h(x)=x^2-2x-24/x^2-9 find all values of x that are not in the domain of h

Answer 1

for h(x) = (x^2-2x-24)/(x^2-9)

x= 3 or -3 are not in the domain, as they make the denoinator = 0

same for

h(x) = x^2 -2x -24/(x^2-9)

but if you really meant

h(x)= x^2 -2x -24/x^2 - 9

then only x=0 is not in the domain
