inverse function

 "x squared such that x is greater than or equal to zero" and "square root of x such that x is greater than or equal to zero"
How can they for mirror image in a graph, illustrate it to me with a numerical example

Re: inverse function

hi Ramesh ra,

This graph will show you:

The blue curve is y = x^2, and the red curve is y = √x

The line y = x is the mirror line that will reflect one curve into the other.  This always happens with a pair of inverse functions.

eg.  (2,4) is on y = x^2   and (4,2) is on y = √x

Hope that helps,

Bob
