Answer:
(a) linear
Step-by-step explanation:
When faced with determining functional relationships from tables, it is a good idea to look at the x-values (usually the first row) to see if they are sequential or have a common difference. Here, the numbers 1, 2, 3, 4 are consecutive, so have a common difference of 1.
Then, look at the y-values (usually the second row) to see if they have a common difference. Here, those numbers, too, are sequential: 4, 5, 6, 7, so have a common difference of 1.
__
When both x- and y-values have common differences, the table represents a linear function.
You have already determined the y-values have a common difference of 1, so you know choice C is inappropriate.
a. Linear: As x increases by 1, so does y.
