Question

Suppose you’re going to graph the relationship between distance (from starting position) and time in the video. Why is it unnecessary to show the graph below the horizontal axis or to the left of the vertical axis?

Answer 1

On the graph, the axes represent time and distance. Neither time nor distance can be negative, so it’s unnecessary to show the graph for negative x- and y-values (to the left of the vertical axis and below the horizontal axis).

Answer 2

Since the x and y axes correspond to time and distance, extending the graph would be unnecessary because time and distance cannot be negative numbers.
