Question

The function f(t) = 349.2(0.98)t models the relationship between t, the time an oven spends cooling and the temperature of the oven.

A 2-column table with 5 rows. The first column is labeled time (minutes)t with entries 5, 10, 15, 20, 25. The second column is labeled oven temperature (degree Fahrenheit) f(f) with entries 315, 285, 260, 235, 210.
For which temperature will the model most accurately predict the time spent cooling?

0
100
300
400

Answer 1

300

Reason: the data temperatures in the table range from 210 to 315°F, so a temperature of 300°F lies inside the observed range and the model will be most accurate there.
