Question 108861:  I really need some help with these two problems. I don't know where to get started or how to get the answer. I thank you so much for all your help!
 
1.Graph the following quadratic equation: f(x)= x^2 + 4x -5 and 
2.Graph the following quadratic equation: f(x)= -2x^2 -8x -6

You can  put this solution on YOUR website! 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 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)
