Exercise 12 Page 2

A typical graphing calculator has a height-to-width ratio of 23. Therefore, the graphing calculator will display a square window if the height and width satisfy this ratio. Height/Width=2/3 Let's find the height (y) and width (x) of the given viewing window. Height:& 3-(-3)=6 Width:& 4-(-4)=8 Now we can use our formula.

Since we ended up with a false statement, the viewing window is not a square.
