The answer to this question is wrong. First of all, a quadratic equation can not have a leading coefficient that is positive and the graph will represent an equation which has a negative coefficient. Secondly, if you look at the graph well it's roots are -1 and 1/3 hence making the solution here wrong as the roots signs have been swapped. Thirdly, in the solution - although it is wrong in the first place - has an error where the signs are interchanged which makes it confusing to the unsuspecting eye.
Finally, the answer should be D. y = 1 - 2x - 3x^2. Please make PROMPT adjustments.
