Question 189134
 how do i graph the logarithmic funtion y=3log5x?
-----------------
Same as with any function.  
You make a table of values.
You pick values of x, and calculate the value of y to find points.
When you have enough points, you draw a smooth line thru them.

dl free software to do this at

it will do the table of values for you, and it will plot the graph (in color).
