zoomBox: 2 views of a function

Dick Lane
Left panel shows a "moderate size" view of function g. The right panel shows a zoomed view that corresponds to the left panel's rectangle with diagonal corners marked by red diamonds. Move those red diamonds to inspect the graph of g more closely.
Use the input box on left panel to enter your own expression for the function to be examined. (The lower-right button will specify an expression involving some fractional powers.)
