Created by Sal Khan. So that is 5 10 15 20 and 25. The graph of y log 10 x is shown in Figure 2.

5 6 2 3. The function y log b x is the inverse function of the exponential function y b x. The graph does not extend to the left of the y-axis and in fact never even intercepts the y-axis.

When x is 125 and y is negative 2-- When x is 125 so 1 is there-- 125 is going to be really close to there-- Then y is negative 2. Every positive number y can be expressed as 10 raised to some power xThis relationship is described by the equation y 10 x and described by this graph. The base 10 logarithm function Background.
