Which represents a function?

A relation is called a function, if there exist a unique value of y for each value of x. It means for each input there exist a unique output. ... In the given table for each value of x, we have unique value of y, therefore the given table represents a function

Step-by-step explanation:

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
