select the answer to the problem: d/dx(3) a. 4 b. -2 c. 0 d. 3

Explanation:

Step1: Recall derivative rule for constant

The derivative of a constant function $y = C$ (where $C$ is a constant) with respect to $x$ is given by $\frac{dC}{dx}=0$. Here, the function is $y = 3$, which is a constant - valued function.

Step2: Apply the rule

For $y = 3$, $\frac{d}{dx}(3)=0$.

Answer:

C. 0
