\[A, \: B, \: k\]can be positive or negative and the sign and magnitude of each determines the shape of the graph.
The graph has an asymptote in the line
\[B \gt 0\], the graph lies above the asymptote. If
\[B \lt 0\]the graph is below the asymptote.
The intercept with the
\[y\]- axis is at
There is no
\[x\]- intercept if
\[A, \: B\]have the same sign. If
\[A, \: B\]have opposite signs then the
\[x\]intercept is at
