Mathematically, this is expressed as #6<=f<11#

Explanation:

We first need to solve each part of this problem:

#f-6<5=>f<11#

#f-4>=2=>f>=6#

The graph, then, will consist of a line along the #f#-axis (probably looking very much like a number line) and will be a solid dot at 6 (to indicate that 6 is part of the solution), a hollow dot at 11 (to indicate that all the points up to but not including 11 are part of the solution), and a solid line connecting the two dots.

Mathematically, this is expressed as #6<=f<11#
