Definition: In mathematics, an asymptote is a line that a curve approaches but never touches. These lines are called asymptotes and they can be used to draw curves without lifting your pencil from the paper. For example, consider the equation y = x^2 + 1. This equation represents a parabola with its vertex at (0, 1). As we move to the right or left of this point, the value of y approaches infinity, indicating that the curve is approaching the line y
