Answer:
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.
Step-by-step 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


Maximum


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.
As the mapping suggests, the first (x) coordinate is decreased by 3, and the second (y) coordinate is increased by 2. So, given the inputs, you have


And yes, this rule is a function: it has a starting set (the domain), which is all possible couples
, and a landing set (the codomain), which is again composed by the couples
. Since for every point in the domain you have one and only one output, this rule is a function.
