26. Since the axis of parabola is x-axis,

The equation parabola is either y2 = 4ax or y2 = 4ax.

Also it passes through (2, 3) which lies in the first quadrant.

So the equation is,

y2= 4ax

Putting x = 2 and y = 3, we set

(3)2 = 4 (a) (2)

a = 98

? The equation of parabola is y2 = 4 *98x

y2 = 92x

2y2 = 9x
