According to the Fundamental Theorem of Calculus (often referred to as the evaluation theorem), if we can identify an antiderivative for the integrand, we can evaluate the definite integral by computing the antiderivative at the interval's endpoints and subtracting.
<h3>How to explain the information given?</h3>
Find the antiderivative of 3x² which is x³.
For example, let's assume that x is represented as 5. The value of the antiderivative will be:
= x³
= 5³
= 125
Now, subtract the value found by plugging in b from the value found by plugging in a to get 125-27 or 98.
