Question

Determine whether the given set is a function or not. Explain.

{(6,-1), (-4,2), (5,2), (4,6), (6,5)}
​

Answer 1

The given set is NOT a function

Explanation:

A function is a given set of data in which no x values repeat, where y values may or may not repeat. Since this given set does have a x value that repeats, it is not a function!

Answer 2

Answer: No.

Step-by-step explanation: A function means that for every x, there is only ONE y value. In this case, 6 can be either -1 or 5, which is more than one value.
