Terms to Know
Asymptote

A line that a curve approaches; the distance between the curve and an asymptote approaches zero.

Horizontal Asymptote

A horizontal line that a curve approaches from above or below; the curve tends towards a constant value, and its distance to the horizontal line tends towards zero.

Oblique Asymptote

Also called slant asymptotes, a line that a curve approaches as x tends towards ± inifinity; it can be defined by y=mx+b, where m≠0.

Vertical Asymptote

A vertical line that a curve approaches from the left or right; the curve tends towards positive or negative infinity, and its distance to the vertical line tends towards zero.
