The relationship between the input and output values in the table can be described as follows: As the input values increase by 1, the output values also increase in a specific manner. For an input of 1, the output is -1; for an input of 2, the output is 0; for an input of 3, the output is 1; and for an input of 4, the output is 2.
This indicates that the output is derived by subtracting 2 from the input value. In other words, the output can be represented by the equation: Output = Input - 2.
Thus, the relationship shows that as you add 1 to the input, the output increases by 1, reflecting a linear correlation between the two.
