Question

sebastian uses a gift card to buy gaming apps. the table shows that the input is the number of games that are $2 each. the output is the amount left on the card. how can you tell if the table shows a function? check if each input has exactly one output. does each input have exactly one output? yes does the table show a function? yes no number of games 0 1 2 3 money on card ($) 25 23 21 19

Explanation:

To determine if a table represents a function, we check if each input (number of games) has exactly one output (money on the card). Looking at the table:

• Input 0 has output 25.
• Input 1 has output 23.
• Input 2 has output 21.
• Input 3 has output 19.

Each input (0, 1, 2, 3) has exactly one corresponding output. By the definition of a function (each input has exactly one output), this table represents a function.

Answer:

Yes
