Question

Could someone help me with this one.
I believe it is a rational function. I got the answer form my exercises I just need a friendly explanation. Thanks! Attachment included

Answer 1

the domain is all numbers except those what would make the denominator zero, because you cannot divide by zero
find the domain by solving \[x^2-36=0\] for \(x\) and the say "all real numbers except those"

Answer 2

ok #satelite73
on the homework the answer is \[(-\infty,-6)u(-6,-6)u(6,)\]
Does that means that the domain is no real numbers?

Answer 3
