Learn how to evaluate the integral of a constant

The video tutorial explains the concept of a definite integral, focusing on calculating the area under a curve. It begins with an introduction to the integral's components, followed by a graphical representation of the function F(x) = 4. The tutorial then demonstrates how to calculate the area of a rectangle formed by the function's graph, using the formula for area. The definite integral is determined to have a value of eight. The session concludes with an invitation for questions.

What is the function F(x) defined as in the introduction?

• A linear function

• A quadratic function

• A constant function

• An exponential function

How is the function F(x) = 4 represented on the graph?

• As a vertical line

• As a curved line

• As a diagonal line

• As a horizontal line

What are the endpoints of the definite integral discussed?

• 0 to 2

• 3 to 5

• 2 to 4

• 1 to 3

What is the formula used to calculate the area of the rectangle?

• Area = length + width

• Area = length / width

• Area = length * width

• Area = length - width
