Using GeoGebra to Play with Functions

Have some fun graphing functions!
The function  f  is the solid green graph below; it is initially the absolute value function.
The function  g  is the dashed purple graph; it is initially the reciprocal function.

To begin, click anywhere in the GeoGebra window to make it active.
To change a function, right-click on its formula in the upper left, select EDIT, type in the desired formula, and press ENTER.

Try some of the following! See if you can figure out what some of these functions are doing!

type this...	notes	type this...	notes
x^2, x^3, x^(1/3), etc.	use "^" for powers	(x^2)*sin(x)	use "*" for multiplication
gamma(x)	the gamma function	sgn(x)	the sign function
exp(x)	the natural exponential function	log(x)	the natural logarithm function
cos(x)	the cosine function	sin(x)	the sine function
tan(x)	the tangent function	ceil(x)	the ceiling function
floor(x)	the floor function	round(x)	the rounding function
sin(1/x)	It oscillates wildly near zero!	MIX and MATCH!	HAVE FUN!
