Use the graph below to answer the question that follows: what is the rate of change between the interval of x = 3pi/2 and x = 2pi? a) 4/pi b) pi/4 c) 2/pi d) pi/2

The y value changes from y = 1 to y = 3, which is a change of 2 units. Call this P. So P = 2 = 2/1.

The x value changes from x = 3pi/2 to x = 2pi which a difference of pi/2. Call this Q. So Q = pi/2

Divide P over Q:

P/Q = (2/1) divided by (pi/2) = (2/1)*(2/pi) = 4/pi

4/pi which is choice A

option: d is correct

step-by-step explanation:

1/800 is the right answer
