### Function Project

By: Taylor Lynn

Algebra 1

5th period

Real World Problem
• If Amanda and her 5 friends go to a High School football game, and each ticket cost \$5.00 how much would her total cost be all together?
The Equation
• Y= 5x or F(x)= 5x
• X= the number of friends going with Amanda.
• Y= the total cost.
Independent and Dependent
• My independent variable is my x value which is the number of friends going.
• My dependent variable is my y value which is the total cost.

*Y depends on X

* So the number of friends depends on how much the total cost is.

Domain and Range
• Domain- x value
• Range- y value

Domain= (1,2,3,4,5)

Range= (5,10,15,20,25)

Continuous
• My problem is continuous! My data makes a straight line.
• Amanda could have as many friends as she wants to go to the game and the price would be 5 more dollars.
Is it a Function?
• A function is if all of your x values are different.
• My problem is a function because all of the X’s are different.
