Question

Can anyone help me with the question I attached below?

Answer 1

The range in the average rate of change in temperature of the substance is from a low temperature of -22 ºF to a high of 16 ºF.

Explanation:

Sine function is a bounded function whose range is between -1 and 1. The lowest average rate of change in temperature occurs when sine function is equal to 1 and the highest when this function is equal to -1. Then, the minimum and maximum average rate of changes in temperature are:

Minimum

`f_(min) = -19 -3`

`f_(min) = -22`

Maximum

`f_(max) = 19-3`

`f_(max) = 16`

The range in the average rate of change in temperature of the substance is from a low temperature of -22 ºF to a high of 16 ºF.
