Is the function increasing or decreasing over the interval [2, 7]? Find the
rate of change over this interval.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

the answer is stop cheating on things stoopid

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
