We are given points on trig graph as

(0,-4)

$((\pi)/(2) ,0)$

$(\pi ,4)$

$((3\pi)/(2) ,0)$

$(2\pi ,-4)$

now, we can find rate of change from x = π to x = 2π

so, we will select two points

$(\pi ,4)$ and
$(2\pi ,-4)$

we can also write as

$a=\pi , f(a)=4$

$b=2\pi , f(b)=-4$

now, we can use average rate of change formula

A=(f(b)-f(a))/(b-a)

now, we can plug values

and we get

$A=(-4-4)/(2\pi -\pi)$

$A=(-8)/(\pi )$

so, option-C.............Answer
