Question
Can you show me how to do this please?


Plot the graphs of the following functions

1.   f(x)=7x
2.   f(x)=4x - 3
3.   f(x)=(1/5)x
4.   f(x)= log3x  

Answer
I cannot graph them for you but it's simple to graph them.  The first three are straight lines and it only takes two points to draw a straight line.  For example, for 1. f(0) = 0, f(1) = 7.  Plot those and draw a straight line between them.  Same deal for 2. and 3.
For 4., you won't get a straight line so it depends on how many points you want to plot.  I assume you mean f(x) = log(3x).  
So f(1) = 0.477, etc.
