I need the answer to this question for my physics class

The graph of the equation k = 1:2 + b: + c, which describes how the height, h, of a hit baseball changes over time, t, is shown below. h height 1' 0 time If you alter only this equation's c term, which gives the height at time t = 0, the alteration has an effect on which of the following? I. The h-intercept II. The maximum value of I: III. The t-intercept I only II only III only I and III only I, II, and III weeps
