Determine if the parabola opens up or down. y = 1 2 x 2 − 5 x y=\frac12x^2-5x

In order to determine if this parabola opens up or down, we simply need to look at the sign value for our a value, which here is positive one half. And since it is positive, that means that this parabola is going to open upward.
