Answer: Last option.
Step-by-step explanation:
By definition, a relation is a function if and only if each input value has an unique output value.
For this exercise it is important to remember that the input values are the values of "x" and the ouput values are the values of "y"
Knowing this and given the tables attached which represent the functions [tex]f(x)[/tex], and [tex]g(x)[/tex],, you can identify that:
1. In the table that represents the function [tex]f(x)[/tex], the input value 1 produces the output value 3.
2. In the table that represents the function [tex]g(x)[/tex], the input value 1 produces the output value 3.
Therefore, based on this, you can determine that the input value that produces the same output value for the two functions is:
[tex]x=1[/tex]
