The equations given between the options of projects of a parabola with different lengths of latus rectum. This means that in order to determine which of the graphs of the projects of the most narrow and the most broad among all, we can compare the absolute value of the coefficient before x2. The more narrow is the smaller, therefore, f(x) = 0.5x2 and the higher is f(x) = –10x2
