Set up equation
Factor out an x
Set x-2b=0
So our zeroes are
When we graph our parabola, our y intercept will be at (0,0) and (0,2b).
Our axis of symmetry will be at
since we did -b/2a
Our extreme values for this function is a minimum value since our leading factor coefficient (1) is greater than zero.
so plug in b f
into the equation at the very top will give us our minimum.
so our miniumum value is
