Question

What is the domain of the following parabola?

Answer 1

do you know how to find the domain of a parabola? is this multiple choice?

Answer 2

isn't it the first one?

Answer 3

mmm..well think so because 3 is a y value on the graph...

Answer 4

but I thought the domain was the x value and the x value peaks at 2

Answer 5

ik, im just saying that the answer you picked in the picture is wrong and that its prob x is equal too -1 tho

Answer 6

so it would be the second one? or the first?

Answer 7

the second one because it cant be x is greater than or equal too 2 because the parabola opens down and any number greater than 2 wouldn't be in the parabola so its -1...I hope that made sense XP

Answer 8

oh yes I get it thanks a lot!

Answer 9
