Answer:
A. No, it does not pass the vertical-line test..
Step-by-step explanation:
A. is the correct answer, as functions cannot have the same x value correspond to different y values. For a function to be considered a function, it must always pass the vertical line test.

Answer:
is the degrees value of
.
Step-by-step explanation:
We are given the following details about the angle
:
![\theta =\dfrac{8\pi}{9}\text{ radians}](https://tex.z-dn.net/?f=%5Ctheta%20%3D%5Cdfrac%7B8%5Cpi%7D%7B9%7D%5Ctext%7B%20radians%7D)
It is know that the relation between radians and degree units is as follows:
![\pi \text{ radians} = 180 ^\circ](https://tex.z-dn.net/?f=%5Cpi%20%5Ctext%7B%20radians%7D%20%3D%20180%20%5E%5Ccirc)
We can use simply use unitary method to convert radian value of
to degrees.
![\pi \text{ radians} = 180 ^\circ](https://tex.z-dn.net/?f=%5Cpi%20%5Ctext%7B%20radians%7D%20%3D%20180%20%5E%5Ccirc)
![\Rightarrow 1 \text { radian}= \dfrac{\pi}{180} ^\circ](https://tex.z-dn.net/?f=%5CRightarrow%201%20%5Ctext%20%7B%20radian%7D%3D%20%5Cdfrac%7B%5Cpi%7D%7B180%7D%20%5E%5Ccirc)
![\Rightarrow \dfrac{8\pi}{9} \text{ radians} = \dfrac{180}{\pi} \times \dfrac{8\pi}{9} ^\circ\\\Rightarrow \dfrac{180 \times 8}{9}^\circ\\\Rightarrow 20 \times 8^\circ\\\Rightarrow 160 ^\circ](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7B8%5Cpi%7D%7B9%7D%20%5Ctext%7B%20radians%7D%20%3D%20%5Cdfrac%7B180%7D%7B%5Cpi%7D%20%5Ctimes%20%5Cdfrac%7B8%5Cpi%7D%7B9%7D%20%5E%5Ccirc%5C%5C%5CRightarrow%20%5Cdfrac%7B180%20%5Ctimes%208%7D%7B9%7D%5E%5Ccirc%5C%5C%5CRightarrow%2020%20%5Ctimes%208%5E%5Ccirc%5C%5C%5CRightarrow%20160%20%5E%5Ccirc)
Hence, ![\theta = 160^\circ](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20160%5E%5Ccirc)
