The function f(x) = x^2+4 is defined over the interval (-2,2). If the interval is dived into n equal parts what is the height of the right endpoint of the kth rectangle?

Option (A).

Step-by-step explanation:

The function f(x) = x² + 4 is defined over the interval (-2, 2)

Total number of equal parts between this interval = 5

If the interval is divided into n equal parts, height of the right endpoint of each rectangle =

Height of the endpoint of the k rectangles =

Therefore, height of the endpoint of the kth rectangle = Height of first rectangle + height of k rectangles

= -2 +

Option (A). will be the answer.

6 meters
