Which function does the graph represent? {See attachment for graph).
Given answers are here. But, if you could help me figure out how to get the answer, I'd appreciate it.
It's the last one... now to explain that uhmm
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.
That leaves you with options D and E
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
Thank you so much. :-) I'll try to remember these things. So easy to forget.
