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

Limits:

The negative end of the x-axis is the horizontal asymptote at t minus infinity.
The positive end of the x-axis is the horizontal asymptote at t infinity.
The line x = −1 is the vertical asymptote at t equal to −1 (the upper end at −1 from the right, the lower end at −1 from the left).
Possible oblique asymptotes at t = 1. Try it:

Thus y = x/2 − 3/4 is the asymptote at t = 1 (its left end at 1 from the left, its right end at 1 from the right).
Picture:

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