Parabola equation in polynomial form

The vertex of an up-down facing parabola of the form y=ax²+bx+c is x_v=−b2a

Rewrite y=(x−2)²−9 in the form y=ax²+bx+c

y=x²−4x−5

The parabola parameters are:

a=1, b=−4, c=−5

x_v=−b2a

x_v=−(−4)2· 1

Simplify

x_v=2

Plug in x_v=2 to find the y_v value

y_v=−9

Therefore the parabola vertex is

(2, −9)

If a<0, then the vertex is a maximum value
If a>0, then the vertex is a minimum value
a=1

Minimum (2, −9)
