A parabola has vertex (2, 3) and contains the point (0, 0). find an equation that represents this parabola.

AfilCa [17]

First write it in vertex form :-

y= a(x - 2)^2 + 3 where a is some constant.

We can find the value of a by substituting the point (0.0) into the equation:-

0 = a((-2)^2 + 3

4a = -3

a = -3/4

so our equation becomes y = (-3/4)(x - 2)^2 + 3

Add 1 on both sides.

We get:

-2x = -6

Now divide -6 by -2...

-6/-2 = 3
