Question
If $y = \int f(x)dx + C$, then $f(x)dx$ is called the -----.
Correct Answer
Option D is the correct answer.
Detailed Explanation
In an integral of the form $\int f(x)dx$, the function $f(x)$ is called the integrand, and the expression $f(x)dx$ (which includes the differential $dx$) is often referred to as the integrand element or simply the integrand in general context. Therefore, $f(x)dx$ is called the integrand.
Hint
Recall the terminology associated with integration. What are the parts of the integral notation called?
