a parabola has a vertex at (0,0). the focus of the parabola is located on the positive y - axis. in which direction must the parabola open? up down left right

a parabola has a vertex at (0,0). the focus of the parabola is located on the positive y - axis. in which direction must the parabola open? up down left right

Answer

Answer:

A. up

Explanation:

Step1: Recall parabola - focus relationship

For a parabola with vertex at the origin ((0,0)), if the focus is on the positive (y -)axis, the standard - form of the parabola is (x^{2}=4py) ((p>0)).

Step2: Determine opening direction

The general rule is that for the parabola (x^{2} = 4py) ((p>0)), it opens upwards.
