18: Symmetry: None.
Intercepts: (0,0) for t = 1.

Limits:

The positive end of the x-axis is the horizontal asymptote at time infinity. The negative end of the y-axis is the vertical asymptote at time 0 from the right.

Picture:

Next investigate directions in which the curve goes and mononoticity of the resulting graph, inclusing "interesting" points.
