4-73.

The graph at right shows the velocity of an object over time defined by the function .

Use your graphing calculator to evaluate

. What does the result in part (a) calculate?

You just calculated the area under a velocity graph.

What does

represent? Translation 1: What is the derivative of a velocity function?

Translation 2: What is the slope function of a velocity function?Translation 3: If velocity is the derivative of position, then what is the derivative of velocity?

What will the units be in part (c)?
