Question 181932
Plot the graphs of the following functions. 
f(x) = 5x 
f(x) = 4x+2 
f(x) = (1/3)x 
f(x) = log5x 
How do I get the solutions for each of these functions?
------------------------
There are no solutions.  Each of these functions will be a line of infinite length and all points on the line belong to the function.
