Evaluate the definite integral by using the formula of a trapezoid

The video tutorial explains how to graph a linear function, focusing on identifying the y-intercept and slope. It then transitions to discussing the area of a trapezoid, emphasizing the correct identification of bases and height. The instructor demonstrates how to rotate the figure to better understand the trapezoid's orientation and calculate its area using the formula: area = 1/2 * (base1 + base2) * height.

What is the y-intercept of the function F(x) = x + 2?

• 2

• 0

• 1

• 3

What is the slope of the function F(x) = x + 2?

• 1/2

• 3

• 1

• 2

Which of the following is NOT a base of a trapezoid?

• The two parallel sides

• The bottom side

• The non-parallel sides

• The top side

What is the correct formula for the area of a trapezoid?

• Base1 + Base2 * Height

• 1/2 * Base1 * Base2 * Height

• 1/2 * (Base1 + Base2) * Height

• Base1 * Base2 * Height

If the bases of a trapezoid are 5 and 2, and the height is 3, what is the area?

• 10.5

• 21

• 15

• 7.5
