Its the y set of values

The right side is the y values

celinegirl · Answer

@pooja195 wait! i just saw that it said range. Oops! lol

celinegirl · Answer

@pooja195 so its B? because i was told that you can't use the same number twice

pooja195 · Answer

Im not sure about that...I was thinking D since it lists all the numbers maybe @sleepyhead314 or @nevermind_justschool can confirrm?

pooja195 · Answer

Or @Astrophysics ;-;?

astrophysics · Answer

You don't want any repeating numbers, in your interval, so you would leave it as {-5,-4,2}

astrophysics · Answer

But you have the right idea :)

pooja195 · Answer

So @celinegirl you are correct its B :) sorry for the confusion
