Answer:
The range in the average rate of change in temperature of the substance is from a low temperature of to a high of .
Step-by-step explanation:
In the sinusoidal function , represents the amplitude and represents the equation of the midline.
By definition sinusoidal functions ebb and flow with respect to this midline. Therefore, the minimums must occur at and the maximums must occur at .
Thus, the minimum, or low, occurs at and the maximum, or high, occurs at .
There was a change of 17 degrees
12 - 17 = -5
7
Set up an equation: x ^2 -3x=28
simplify to a quadratic equation. You would then solve and get x=7
(x -infinite<x<infinite)
