A certain quadratic function describes the height of a baseball as it is thrown. If a word problem asks you to find the maximum distance thrown, what point on the graph would you be looking for?

x-intercept

(No, not the maximum because that would be the largest HEIGHT. largest DISTANCE would be the largest x value. Since height must be positive, the largest x value with non-negative height is the largest x-intercept)
