Example 3 ANIMALS Blue whales can reach a top speed of 30 miles per hour. The equation d = 30t describes the distance d that a whale swimming at that speed can travel in time t. Assuming that a whale can maintain the speed, represent the function with a graph. Step 1Select any four values for t. Select only positive numbers because t represents time. Make a function table.
