f(x)=a(x-r)(x-s)

roots (x intercepts) x=r and x=s

axis of symmetry = (r+s)/2

vertex= ( (r+s)/2 , y )

Applying Quadratic Models

f(x)=a(x-h)^2+k

EXPAND

f(x)=ax^2+bx+c

c is the "y intercept"

the vertex is always (h,k)

"K"

the parabola moves "k" units up or down

"h"

value of "h" is the axis of symmetry

the parabola moves "h" units left or right.

"h" is negative, parabola moves rigt

"h" is positive, parabola moves left
