Question

The data in the table represent the height of an object over

time.
Which model best represents the data?

Height of an Object

Time (seconds) Height (feet)
05
1
50
2
70
3
48
quadratic, because the height of the object increases or
decreases with a multiplicative rate of change
quadratic, because the height increases and then
decreases
exponential, because the height of the object increases
or decreases with a multiplicative rate of change
exponential, because the height increases and then
decreases

Answer 1

B

Explanation:

Answer 2

The correct answer option is quadratic, because the height increases and then decreases.

Explanation:

We are given the following data in the table which represents the height of an object over time:

Time (s) Height (ft)

0 5

1 50

2 70

3 48

We know that in situation where the values increase and then decreases, a quadratic model is used.

From the values given in the table, we can see that the values of height first increased and then decreased with the increase in time.

Therefore, the model used is quadratic, because the height increases and then decreases.
