In Calculus, today, I received a fairly difficult project -- probably not as hard as you would think, but I do need help. We are asked to create one picture on our Graphing Calculators. I have done about 11 so far, but none are as I like them.
This is what I put into the Y Values:
Y1= Ö(81-X )
Y9= -.7abs X+12
*Note: The Ö symbol stands for the square root symbol. The big 2s at the ends of the Xs stands for "squared". I couldn't find a way to make them smaller.
Here are my window values:
This should produce a smiley face. Can you show me some of your graphics and formulas you have used? I would greatly appreciate it!
