Function:	PDFF(,,)
	X-axis	Y-axis
Minimum:	Minimum X	Minimum Y
Maximum:	Maximum X	Maximum Y

Enter the argument(s) for the function, including the symbol x.
Enter the minimum and maximum for the X-axis and for the Y-axis.
To let the software define the Y-axis automatically, leave both input fields for the Y-axis empty.

CDFF(x,df1,df2)

CDFF(x,df1,df2) returns the value at x of the F cumulative distribution with degrees of freedom df1 and df2.
