Question 16555
I need to add a note to the previous solution that was posted to this problem.  The range of f(x)= 1/(x-4) is NOT all real numbers.  If you draw the graph of y=1/(x-4) you will notice that the value of y can approach zero, but it will NEVER equal ZERO!  So the range turns out to be all real values of y NOT EQUAL TO ZERO!

Consider the graph:

{{{ graph (300, 300, -10, 10, -10, 10, 1/(x-4)) }}}
