Question

Which function does the graph represent? {See attachment for graph).

Answer 1

Given answers are here. But, if you could help me figure out how to get the answer, I'd appreciate it.

Answer 2

It's the last one... now to explain that uhmm

Answer 3

look at the parabola part of the graph. Ignore the part before that. The parabola is curving up, so it has to have a positive leading coefficient.

Answer 4

That leaves you with options D and E

Answer 5

Now the parabola starts 4 units below the x axis, thus it has to be 2x^2 - 4, if it started above the x axis you would have +4 instead of -4, so that leaves you with E

Answer 6

Thank you so much. :-) I'll try to remember these things. So easy to forget.
