Funny Face Graph using Parent Functions

  1. Sep 26, 2010 #1
    1. The problem statement, all variables and given/known data
    Create a funny face using the specified parent functions.

    2. Relevant equations
    Square root
    Absolute value

    3. The attempt at a solution
    I realized that I can use the square root function as eye brows and maybe a semicircle as a chin or partial nose, but I have a problem bringing everything together. Thank You

    Once you know what kind of functions you're going to use for what, try drawing it on a graph. Then for each individual piece, look at what you've drawn vs. what the graph of, for example, a normal [tex]y=\sqrt{x}[/tex] graph looks like. You'll need to shift the graph horizontally and vertically, as well as maybe stretch it horizontally and vertically to make it fit where you want it to
