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 the expression ( \int f(x)dx ), ( f(x) ) is called the integrand. While ( f(x)dx ) is more precisely the 'differential element' or 'integrand expression', among the given options, 'integrand' is the most suitable term to describe ( f(x) ) which is the core function being integrated.
Hint
Recall the definitions of the components of an integral. What is the function being integrated called?
