\[A, \: B, \: k\]can be positive or negative and the sign and magnitude of each determines the shape of the graph.
The grapha has an asymptote in the line
\[k \gt 0\], the graph lies to the right of the asymptote. If
\[k \lt 0\]the graph is to the left of the asymptote.
The intercept with the
\[x\]axis is at
