Question 108861
LET Y=X^2+4X-5 (RED LINE)
LET Y=-2X^2-8X-6 (GREEN LINE)
NOW ASSIGN VALUES FOR X TO FIND THE Y VALUES AND PLOT THEM TO FORM THE CURVES/LINES. 
{{{ graph( 300, 200, -6, 5, -10, 10, y = x^2 +4x -5 , y = -2x^2 -8x -6) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = x^2 +4x -5 and y = -2x^2 -8x -6).
some red curve points are: (-5,0),(1,0)
some green curve points are: (-3,0),(-1,0),(-2,2)
