State which of the following sets of ordered pairs represent a function. set a: (5, 2), (4, 3), (3, 4), (2, 5) set b: (-1, -6), (0, 2), (1, 2), (3, 6) set c: (2, 1), (4, 2), (2, 3), (8, 4) a. set c b. set b c. set a d. set a and set b select the best answer from the choices provided

Sets A and B . choice D

Step-by-step explanation:

A relation from a set X to a set Y is said to be a function if each individual element of X is related to exactly one element in Y. In other words, given an element x contained in X, there is only one element in Y that x is related to.

Going by this definition, Sets A and B are functions since each element in x is related to exactly one element in y.

On the other hand, Set C is not a function since the element x = 2 has two corresponding y elements, 1 and 4

sets A and B

Step-by-step explanation:

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
