Answer:
Option B.
Step-by-step explanation:
A function is represented by the table given in the question.
We should always remember that for a function plotted on a graph or table representing x and y-coordinates, x value will always represent Domain and y- values define the range of the function.
Therefore x values {2, 4, 6, 8} represent the domain of the function and y values represent the range.
Option B. {2, 4, 6, 8} is the answer.
