Math's a tool not a terror

You have to find a first. You can not assume that a is 1. So if you bring 1/2 into your equation, it should be one that goes through all of those points. y= 1/2x^2 -27x -116. I just left it in intercept form bc it was not specific which form was needed. y=1/2(x+4)(x-58).

Agreed and thanks Katie took a while for the website to post my update. I need to update the entire answer since without doing a first you get the wrong parabola. I get messages to try again or just stick at loading..... often not sure why.

Personally, I didn't understand. It is from my math quiz.
