What is the domain of the following parabola?

Answer 1

a. x ≥ 1
b. x ≤ 1
c. All real numbers
d. y ≤ 2

Answer 2

I'm not sure what the answer is, cause I've been having trouble with determining domains. My lesson never really covered it.

Answer 3

the domain is all the x-values in which the function exists

Answer 4

look at your x-axis and scroll up and down with your eyes for each value on the x-axis
and if you see a part of the curve (line or whatever) there then the function exist and so that number is apart of the domain

Answer 5

for example does your function exist at x=-2?
