Question 48193
Below is the graph of y=x^2-1 you don't want to convert the equation just graph it when you "swap" x and y the shape of the graph is the same but it rotates 90 degrees to the right.  Also remember that x=y^-1 is not a function (it fails the vertical line test)  The software only graphs functions.  

{{{ graph( 300, 200, -6, 5, -10, 10, x^2-1) }}} 

The point of this problem is to realize that the shape of the graph stays the same but that it rotates.  Please let me know if you need more help with this problem
