After reviewing this problem I think that I understand it. Can someone please explain.
My first step was to rephrase the question... and put it in the format of
y=mx+b
y=x^2+bx+ax+ab
afterwards, statement once gives me what a+b=-1
so y=x^2 x(a+b) +ab or y=x^2-x+ab
ab is y intercept but still do not know what the graph exactly looks like.
statement 2 give you ab (gives y intercept) so they are both needed. To get a conceptual graph of y=x^2-x-6
C is answer.
Is there a faster way? or a way to recognize that both stems are needed without having to do the algebra.
Thanks!
