Is the Function Invertible
(By Thomas Scofield)
\textrm{This app displays the reflection across the line } y=x
\textrm{ of those points on the }\newline
\textrm{graph of } y = f(x) \textrm{ with }
x-\textrm{coordinate in the
interval } [a, b]. \textrm{ The graph of } f \textrm{ is
green,} \newline
\textrm{while the reflected points are purple. Can you make a
sketch yourself of the reflected } \newline
\textrm{curve before displaying it? Can you anticipate whether }
f \textrm{ on the domain } [a, b] \textrm{ is } \newline
\textrm{invertible before displaying the reflected points?}
