Tables and Functions #31

Vocabulary A function is a rule that relates two quantities so that each input value corresponds exactly to one output value.

Example 1 Write an equation for a function that gives the values in the table. Use the equation to find the value of y for the indicated value of x. 16 13 10 7 4 y 3 2 1 x

FYI You can write equations for functions that are described in words.

Example 2 Write an equation for the function. Tell what each variable you use represents. The height of a painting is 7 times its width.

Example 3 Write an equation for the function. Tell what each variable you use represents. A large pie costs $2 more than a small pie.

Real-world Application The school band tracked the number of tickets sold and the total amount of money received. They sold each ticket for the same price. They received $60 for 20 tickets, $66 for 22 tickets, and $81 for 27 tickets. Write an equation for the function.
