exercises 3.1 defining the derivative score: 0/27 answered: 0/12 question 1 textbook videos + if $f(x)=14$, find $f(-9)$. question help: video message instructor submit question jump to answer

Explanation:

Step1: Recall derivative rule for constant

The derivative of a constant function $y = C$ (where $C$ is a constant) is $y'=0$. Here $f(x)=14$ is a constant - function. So, $f'(x) = 0$ for all $x$.

Step2: Evaluate at $x=-9$

Since $f'(x)=0$ for all $x$, when $x = - 9$, $f'(-9)=0$.

Answer:

$0$
