Question
The table provides data on the distance (in yards) of a dog from a park entrance as a function of the number of seconds since the dog entered the park. 

| Change in the number of seconds since the dog entered the park | The number of seconds since the dog entered the park | The distance (in yards) of a dog from the park entrance | Change in the distance (in yards) of a dog from the park entrance | Average rate of change of the dog’s distance with respect to time |

Tasks:
a. Complete the table of values above.

b. Sketch a graph of the number of yards the dog is from the park entrance in terms of the number of seconds since the dog entered the park. (Be sure to label your axes).

c. Describe what these average rates of change tell you about how the distance of the dog from the park entrance is changing over the time interval from \( t = 0 \) to \( t = 7 \) seconds.

d. Is your graph concave up, concave down, or some combination of both on the interval \( 0 < t < 7 \)? Justify your answer from part (a) and (c).
