Question

Use a graph of the function to explain the geometric meaning of the value of the integral.

Answer 1

General Idea:

The definite integral of a function f(x) from a to b is given below:

$A=\int\limits^b_a {f(x)} \, dx$

Here geometrically, the value of integral A is the area under the curve f(x) from x = a to x = b
