Function Problem Project

By kallie phillips


My real word problem
My Real Word Problem

  • Rob and his girlfriend and their three friends want to go see step up 3d at the movies. If the tickets cost $5.00 each then how much will it cost total?


The equation
The Equation

  • My equation for my problem is:

    y=5.00x or f(x)= 5.00x

  • X=the number of movie

  • Y=the total cost


Independent and dependent
Independent and Dependent

  • The independent variable is x, which is my number of movie tickets.

  • The dependent variable is y, which is the total cost.

  • “y” depends on “x”

    So the total cost depends on the number of tickets



Domain and range
Domain and Range

  • Domain- x values

  • Range- y values

    d:{1,2,3,4,5}

    r:{5.00, 10.00,15.00,20.00, 25.00}


Continuous or discrete
Continuous or Discrete

  • My data is discrete because it contains only points.

  • We would only use numbers that are like 1,2,3,4 and so on. Not anything between these.


Function
Function?

  • A function is where the x values do not repeat.

  • My x values don’t repeat, therefore it is a function.



Answer
Answer

  • Sooooo….. It would cost up to $25.00 without a coke or popcorn.
