True or False A parabola of the form f(x)=ax^2+bx+c can open up, down, left, or right on a standard graph

OpenStudy (mertsj):

False. If it opens to the right or left there will be a y^2 term.

OpenStudy (anonymous1):

It only opens up or down. It opens up if a > 0, and down if a < 0. It can't open left or right.

OpenStudy (anonymous1):

Therefore, false.
