Question

Use the graph below to answer the question that follows: graph of the curve that passes through the following points, 0, 3; pi over 2, 5; pi, 3; 3 pi over 2, 1; 2 pi, 3. What is the rate of change between the interval of x = 0 and x = pi over two? 2 over pi pi over two pi over four four over pi

Answer 1

Given two points: (0, 3) and (pi/2, 5)

rate of change between x = 0 and x = pi/2

= (5-3)/(pi/2-0)

= 4/pi

Answer 2

X1=0, y1=3
x2=pi/2, y2=5

rate of change = (y2-y1)/(x2-x1)
=(5-3)/(pi/2-0)
=4/pi

ans is D. four over pi
