what 2 numbers multiply to 1 and add to -2? -1 and -1
(x-1)(x-1)=0
set to zero
x-1=0
x=1



vertex
get into y=a(x-h)^2+k form
how nice, it is actually
y=1(x-1)^2+0
the vertex is (1,0)
and since 1 is positive, it opens up and the vertex is a minimum


range is the y values
the min value is y=0
max is inifnity
range is from 0 to infinity

domain is the numbers you can use
