Question
![**Problem Statement:**
Compute the instantaneous rate of change of the function at \( x = a \).
Given:
\[ f(x) = 23 - 6x, \quad a = -6 \]
**Options:**
- A. \(-6\)
- B. \(-36\)
- C. \(17\)
- D. \(36\)
**Explanation:**
The instantaneous rate of change of a function at a particular point is given by the derivative of the function evaluated at that point. For the function \( f(x) = 23 - 6x \), the derivative \( f'(x) \) is the coefficient of \( x \) in the expression, which is \(-6\). Thus, the instantaneous rate of change at \( x = a = -6 \) is \(-6\), matching option A.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa3f191a8-a1b2-42ed-ac9e-32d60645d728%2F8010c189-d64e-4f0c-a5c1-94a7837c0a5c%2Fe04gotf_processed.jpeg&w=3840&q=75)
