Question 297579: My child is in pre-al. She is trying to complete an xtra credit project. She is , from my understanding, looking for a graph that would trick you. I guess she is saying if you stretch the graph vs. keeping it basically a box type graph. Do you see what I am saying? Can you help me or point me to where I could print something out. I pretty much do not know what I am looking for.

Here's a graph of a circle.

graph%28600%2C600%2C-10%2C10%2C-10%2C10%2Csqrt%2836-x%5E2%29%2C-sqrt%2836-x%5E2%29%29

Here's a graph of the same circle.

graph%28600%2C600%2C-10%2C10%2C-20%2C20%2Csqrt%2836-x%5E2%29%2C-sqrt%2836-x%5E2%29%29

In the first graph it looks like a circle.

In the second graph it looks like an ellipse.

All I did was change the scale of the vertical axis (the y-axis).

In the first graph the x and y axis spanned from -10 to 10.

In the second graph, the x axis spanned from -10 to 10 and the y axis spanned from -20 to 20.

If you are not aware of the scaling of each axis, you can definitely be misled by what's on the graph.
