The first table is a function
Explanation:
Given:
Table of values for x and y
To find:
the table that represents a function
For a table to be a function, each of the input (x values) will have only one output (y values)
The table that will represent a function will not have more than one output for an x value
a) Each of the inputs appears only one
The table is a function
b) -5 appears twice on the x value. Hence, it is not a function
c) -2 appears twice on the x value. Hence, it is not a function
d) -4 appears twice on the x value. Hence, it is not a function
