Change the coefficients of the first degree term and the constant on the equation supplied below to find the quadratic equation that goes through the shown x - intercepts, y - intercept, and vertex. The coefficient of the second degree term is -1. Hint: Start by trying to find the y - intercept as that will give you the constant term. Then change the first degree term until the grey parabola goes through all four points. Write down the equation that fits all four points and turn this in to your instructor.
