Factored Form

Factored form is the second form you will learn in the Quadratics Unit. The formula for this is: y=a(x-r)(x-s).

 

•  the value of a will give you the shape and direction of opening of the graph

•  the value of r and s give you the two x-intercepts (r, 0) and ( s, 0)

•  to find the y-intercept: (0, y) you will need to set x=0 and solve for y

•  to find the vertex, use the x-intercepts to find the AOS { (s+r)/2 } and sub the x value into the equation and then solve for y
