# Graphing calculator scene project

## Homework Statement

okay so im doing a graphing calculator project where i have to create some kind of scene, using a ti 84+, and so far i have created a boat and waves, and i cant seem to figure out how to make a small fish (supposed to be in quadrant 3) and also a flag (for the boat) and birds at the top...i know for the birds you can use absolute value but i dont know what numbers to plug in because i dont have my calculator on me...so pleease help me, this project is due tomorrow! and thank you so much in advance <3

## The Attempt at a Solution

these are the functions i have so far

y=.05x2-9 restrictions (x>-9 and x<12)

y=-.05x2-9 restrictions (x>-9 and x<12)

y=sin(x)
y=cos(x)
y=Ö(1-X^2)
y=-Ö(1-X^2)
y= (999,9999,999)*(x-2)

if you can help me improve these also, thatd be awesome, thanks :)

For fish you could simply use a circle, ellipse, parabola etc. with a suitable range restriction to create the shape of a child's depiction of a fish.

Example,

$$y=x^2+6x+7$$
$$y=-x^2-6x-10$$

restriction of $$-4<x<\frac{-6+\sqrt{2}}{2}$$

and then to finish off the tail, you can use x=-4 or maybe another suitable parabola if you like.

For the flag well the pole is simply x=a and y=b to create an elongated rectangle, you can use a stretched out sine curve for the wavy flag, maybe with an ellipse or very fat side-ways parabola to connect the flag between the joints where it is attached to the pole, and finish off with another x=a line to complete the flag shape. As for the birds, honestly, I can't visualize what they're meant to look like

Your teacher assigned this? Yours must of been nicer than mine - mine discouraged drawing pictures on calculators.

I don't necessarily think that one teacher is nicer than the other because of this, but rather what each of them think would be an effective learning tool. I for one find it quite neat. It can be somewhat fun to see you progressing along and it also makes you think to try and use your graphing skills and tests your knowledge of how graphs work.

You don't need to do this. If you want a vertical graph going through the x-axis at 2, then all you need is x=2.

I find it neat too. I just did used it as a distraction instead of an assignment

Learning for fun can never be a bad thing

Better that than distracting yourself by drawing pictures on the table. Where's the math in that haha
