This corresponds to the x -values where f (x) is 0 in function notation. Select all the proportional relations. What is the domain of the given function? Which of these is another way to write the function f(x) = 16x ? answer choices The mapping represent y as a function of x, because each y-value corresponds to exactly one x-value. |Input|Output |1|3 |1|5 |2|30 |2|50 B. Telehealth/Telemedicine COVID. Select all that apply a. An Optional step, if you want, you can omit the middle column from your table, since the table of values is really just the x and y pairs . |x| -1| 0| 1| 2| 2| 3 |y| 1| 2| 3| 4.5| 5.5| 8 A. 12 10 10 6. \hline what is the degree of the power function represented in the table?
