Given a Parabola that intersects the x-axis at x=3 and x=9.
I presume you want to determine the equation of the parabola.
You can use this form:
Given roots of a parabola, the equation of the parabola is derived using the formula:

The equation of the parabola is:

1. Subtract 3x from both sides
2y = 18 - 3x
2. Divide both sides by 2
y = 18 - 3x/2
3. Factor out the common term 3
y = 3(6 - x)/2
