921.      True or False: Polynomial functions, sine, and cosine functions have no horizontal or vertical asymptotes.

True or False: Trigonometric functions csc, sec, tan, and cot have vertical asymptotes but no horizontal asymptotes

1035. It is obtained by taking the limit as y→∞ or y→ -∞.

1. It is a line of the form x = k.

1. It will never cross the curve.

True or False: If a function has a horizontal asymptote, then it cannot have a slant asymptote and  vice versa.

1031. It is a line of the form y = k.

It may cross the curve sometimes

1034. It is obtained by taking the limit as x→∞ or x→ -∞.

1. It is a slanting line and hence its equation is of the form y = mx + b.
