The domain is all the x-values you can use with this function. When dealing with a function like this, you need to ask yourself, what would make the bottom equal to 0? Whatever those numbers are, you do NOT want them in your domain.
A fundamental rule is that you cannot divide by 0 or have 0 as a denominator.
So, you solve x^2+6x=0 to find that x=0 or x=-6 would make the denominator 0.
The domain is everything BUT those two values, because they essentially break your function.
There are 3,600 inches in 300 feet.
2x +9 <0
x > -12
2x<-9
2x<-9/2 (9/2 = 4.5)
x >-12
the answer is all integers between -12 and -4.5
-11, -10, -9, -8, -7, -6, -5
