Question 91866
solve and graph the solution set of x^2 - x - 6 < 0
-------------
Graph y = x^2-x-6
If x = -2 y = 4+2-6=0
If x = 3, y = 9-3-6=0
If x= 0, y = -6
-------------------
Plot these three points and draw a parabola thru them.
{{{graph(400,300,-10,10,-10,10,x^2-x-6)}}}
=====================
solving:
x^2-y-6=0
(x-3)(x+2)=0
x=3 or x=-2
=================
