Select either relation (if the set is a relation but not a function), function (if the set is both a relation and a function), or
neither (if the set is not a relation).
a = {(1, 2) (2, 2) (3, 2) (4.2}]
relation
function
neither

Step-by-step explanation:

A={(1,2),(2,2),(3,2),(4,2)}

Domain:{1,2,3,4}

Range:{2}

it is both a relation and a function.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

hope it you

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
