Hello, Link88!
Find and graph the domain of: .
The radicand must be positive.
The denominator is always positive except at (0,1) where the function is undefined.
The numerator must be nonnegative: .
. . This is the set of points on and above the parabola:
The region looks like this:where there is a "hole" at (0,1).Code::::::::::::|::::::::::: *::::::::::|::::::::::* ::::::::::|:::::::::: *:::::::::|:::::::::* *::::::::o::::::::* *::::::|::::::* *:::|:::* - - - - - - * - - - - - - |
