    please, check your answers before post the video. clearly, if you solve the equation for x-intercepts you will get (x+3)(-x+1)=0, which means your intercepts should be (-3,0) and (1,0). plus please try a little harder to draw the parabola. it looks like 3 years old draw that.

    I apologize for this error. This is one of my earlier videos. It was hard for me to draw the graphs using the program I had. I did have the x-intercept in the correct place (-3,0), but I wrote it and stated it incorrectly throughout this portion of the video. Again, I apologize for this and thank you for bringing it to my attention.
