Ответ:
(a)
(b)
Step-by-step explanation:
We have been a function . We are asked to find the instantaneous rate of change of the function and the slope of the tangent line at point .
(a) First of all, we will find the derivative of our given function using product rule.
Now, we will substitute in our derivative function to find slope of tangent line as:
Therefore, the slope of the tangent line is -65 at point .
(b) We know that instantaneous rate of change of the function at a point is equal to the derivative of the function at that point.
We already figured it out that derivative of our given function at is , therefore, the instantaneous rate of change of the function is also at point .
