range – the range is all the __________________________.
function – A relation where each __________________ value (x) is paired with exactly
one ___________________ value (y) is called a function.
Is each relation a function? Use a mapping diagram. Explain your answer.
Example 1: {(0, 1), (1, 2), (1, 3), (2, 4)}
