Because exponential and logarithmic functions are inverses of one another, if we have the graph of the exponential function, we can find the corresponding log function simply by reflecting the graph over the line y=x, or by flipping the x- and y-values in all coordinate points. Let’s use some graphs from the previous section to illustrate what we mean.
Read MoreThe general log rule relates the logarithmic function to an exponential function. It tells us that log_a(y)=x and a^x=y are equivalent, and similarly, that log_a(x}=y and a^y=x are equivalent.
