Answer:

Third option given

Step-by-step explanation:

On a coordinate plane, a parabola opens to the right with a vertex at (0, 0).

use the following x values to plot the associated y values on the x-y plane:

If x = 0, then $y=\sqrt{0} =0$

If x = 1, then $y=\sqrt{1} =1$

If x = 4, then $y=\sqrt{4} =2$

If x = 9, then $y=\sqrt{9} =3$

Join the points and you will find a branch of a parabola opening to the right.
