Question

What is the domain of the following parabola?

u-shaped graph that opens down with a vertex of 2, 3

x ≥ 2
x ≤ −1
y ≤ 3
All real numbers

Answer 1

are you sure it is domain ? not co-domain?

Answer 2

Yeah, it says domain :/

Answer 3

domain is always x values. values of x which makes y values. If x doesn't make y . that x does not count in domain

Answer 4

So what, it'd be D? Since there's no option that correlates with what you said

Answer 5

yeah. I think it can be D. But I am not sure about it. I can't prove If am asked. however, I can say -1<x<5 is the domain since I can see it in the picture

Answer 6

Okay, thanks :)
