yea what do i do afterwatds

#

(x+b)(x+c)
x = -b , x = -c
So with the roots you’ll have b and c
To work out a we can take the co ordinates (2,-8) and plug 2 into each x value and plug -8 for y and then rearrange for a

U mean inflection point? And I don’t think this has anything to do with points of inflection
