Answer :

Since, the vertex is (0, 0) and the axis of the parabola is the x-axis, the equation of the parabola is either of the from y2=4ax or y2 = -4ax.

The parabola passes through point (2, 3), which lies in the first quadrant.

Thus, the equation of the parabola is of the form y2 = 4ax, while point (2, 3) must satisfy the equation y2 = 4ax.


32 = 4a(2)

a = 9/8

Thus, the equation of the parabola is

2y2 = 9x
