Answer 1

Domain is :\[-3 \le x \le 4\]

Answer 2

Well,I guess you should graph it and look?

Answer 3

but i dont know how to get the answer

Answer 4

Are you saying you don't know how to graph y=x^2-9?


Try to compare the this:
The following is a parabola
y=a(x-h)^2+k
where (h,k) is vertex of the parabola
