Investigating Inversions

Use this worksheet to explore the effect of "turning a function upside down"!

This is what happens when you INVERT something - so we are talking here about "reciprocal" NOT "inverse" functions.

Try to discover the rules for inversion - see if you can learn to predict what 1/f(x) looks like if you know f(x).

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and activated. (click here to install Java now)

Use the slider 'a' to change from f(x) to 1/f(x).

Use 'b' and 'c' to play with other linear functions, and 'd' and 'e' to try out some more interesting ones!
