Question

find f(x) for f(x) = 4.
f(x) = □

Explanation:

Step1: Recall derivative rule for constant

The derivative of a constant function $y = C$ (where $C$ is a constant) is 0. Here $f(x)=4$, and 4 is a constant.
The formula for the derivative of a constant function is $\frac{d}{dx}(C)=0$.

Answer:

0
