Describe the meaning of the word function in math then consider the table. Why does this table show a function?

Answer 1

In mathematics, a function is a relation or mapping between sets of inputs and outputs, where each input is related to exactly one output. In other words, for every input value, there is only one corresponding output value.

The table that shows a function demonstrates this concept by clearly mapping each input value to exactly one output value. In the table, no input value is repeated and each input value has a unique output value associated with it. This property of unique input-output pairings is what makes a relation a function in mathematics.
