Answer:
a function is just a comparison between two quantities so when you go to plot the points, the input is x and the output is y.
Because none of the points on the number line are above 0, we know that the points will be negative.
This eliminates the second and third choices, as they contain positive numbers.
The first point, A, is a number less than -0.5 or -1/2
The first choice matches A with -5/16, which is less than -0.5 or -1/2
Therefore, the fourth choice must be the correct answer.
The same as the last question. B the second option.
