Question

A bottle of water is placed in a freezer. The table shows how the approximate temperature of the bottle changes over time. What type of function best models the data in the graph?

Answer 1

Exponential data

If we plot the values on x-y graph, we get exponential curve.

Answer 2

Answer:

Exponential graph.

Step-by-step explanation:

A bottle of water is placed in a freezer. The table shows the approximate temperature of the bottle changes over the time.

Time                0         5        10       15       20

Temperature 25        21.3    18.1   15.4     13.1

Now we take the common ratio of the temperatures given in the table.

common ratio = $\frac{25}{21.3}=\frac{21.3}{18.1}=\frac{18.1}{15.4}=\frac{15.4}{13.1}=1.17$

Therefore the function plotted on the graph will model an exponential graph.
