An exponential graph often has a _________ asymptote.
A logarithmic graph often has a _________ asymptote.
For an exponential graph in the form f(x) = a(b)^x, the point (0, a) can be used to identify the _________ value.
For a logarithmic graph in the form g(x) = log_b(x), the point (b, 1) can be used to identify the _________.
If a logarithmic graph passes through (1, 0), (4, 1), and (16, 2), then the equation is g(x) = log____(x).
