An exponential function of the
form f(x) = ax, where a is a positive
real number not equal to 1, is an example of a one - to - one function. This
means that there should exist an inverse function for the exponential function.
Such inverse functions are called logarithmic functions.
Remember that the exponential
function and its inverse function will be symmetric to each other with respect
to the line y = x. We will examine the domain, range and graphs
of logarithmic functions. In this laboratory, all answers in decimal form should
be to the nearest tenth.
Special Notation for this grapher : log(x)
is used for the natural log of x, and
log10(x) for the log base 10. Also, we currently have an error in the
table. When the logarithm is undefined, the table reports a value of 0.
