# Math Help - How do I graph these two functions when they are undefined?

1. ## How do I graph these two functions when they are undefined?

The question states:
Sketch the graph of each of the functions listed in the first column and fill in the table. If possible, determine the exact value and show your work.

How do I graph them when "b" is not even defined?

f(x) is undefined when is only when x<=0
g(x) has an asymptote at x = 1 ..so it's undefined only when x = 1

That should be easy to sketch

3. You cannot. $\log_b x = \frac{\log x}{\log b}$, so that the logarithm is identical to logarithms of other bases for $x=1$ and no other point. A base must be specified, otherwise there would be no way to graph it.
