Vertical Tangent Line

Definition

A vertical tangent line is a line that is perpendicular to the curve of a function at a specific point and has an undefined slope. It occurs when there is an abrupt change in direction or when the slope becomes infinite.

Absolute Value Functions:

Absolute value functions can also have vertical tangent lines at certain points where they abruptly change direction, similar to other types of functions.

Discontinuity:

A discontinuity is a point where a function is not continuous, meaning there's a break or jump in the graph. It's like encountering a pothole on the road - you have to slow down or change direction.

Derivative:

The derivative of a function represents its rate of change at any given point. When the derivative is undefined at a specific point, it indicates the presence of a vertical tangent line.
