Question 52342
Substitute the x values into the equation and solve for y.  Plot these (x,y) coordinates and connect the dots.  
For x=-3; 
y=-(-3)^2-2(-3)
y=-(-3)(-3)-2(-3)
y=-9+6
y=-3
Plot:(-3,-3)
For x=-2;
y=-(-2)^2-2(-2)
y=-(-2)(-2)-2(-2)
y=-4+4
y=0
Plot:(-2,0)
For x=-1
y=-(-1)^2-2(-1)
y=-(-1)(-1)-2(-1)
y=-1+2
y=1
Plot:(-1,1)
For x=0
y=-(0)^2-2(0)
y=-0+0
y=0
Plot:(0,0)
For x=1
y=-(1)^2-2(1)
y=-(1)(1)-2(1)
y=-1-2
y=-3
Plot:(1,-3)
