The equation y = 3x2 – 5x – 10 as an equation of the parabola can be dissected. It has the term x^2 which means the parabola can either be up or down not left or right as these equations include y^2 only. In this case, the coefficient of x^2 is positive, hence the parabola is going up. Answer is B.
