Y= x Here is how you should approach every graphing problem pick a number for x, say 0 then y=0 now pick x=1 then y=1 now you have two points (0,0) and (1,1) (you only need two points to graph a line so plot those points, connect them and you got yourself your graph )Graphing Logarithmic Functions The function y = log b x is the inverse function of the exponential function y = b x Consider the function y = 3 x It can be graphed as The graph of inverse function of any function is the reflection of the graph of the function about the line y = x So, the graph of the logarithmic function y = log 3 ( xPlot (x,y) = (10,10) on the graph Draw a straight line between them There's your graph The point (x,y) is x units to the right or left of x = 0, and y units up or down from y = 0 If x is negative, you move to the left If y is negative, you move down
