Question

What is the rate of change from x = π to x = 2π? trig graph with points at 0, negative 4 and pi over 2, 0 and pi, 4 and 3 pi over 2, 0 and 2 pi, negative 4

Answer 1

C. negative 8 over pi

Explanation:

Answer 2

The given data is
x 0 π/2 π (3/2)π 2π
y -4 0 4 0 -4

The curve that models the data is
y = -4 cos(x) as shown below.

The rate of change of y from x = π to x = 2π is

`(-4-4)/(2 \pi - \pi ) =- (8)/( \pi )`

Answer:
`- (8)/( \pi )`
