Key Concepts

Concavity

Concavity describes the direction in which a function curves. A function that is concave down has a downward curvature (shaped somewhat like an upside-down bowl), while a function that is concave up has an upward curvature (shaped like a bowl). In the context of calculus, concavity is determined by the sign of the second derivative, where a negative second derivative indicates concave down and a positive second derivative indicates concave up.

Inflection Point

An inflection point is a point on the graph of a function where the concavity changes from up to down or from down to up. In problems where a function changes concavity—a shift from concave down to concave up, for instance—the point at which this change occurs is known as an inflection point.

Monotonicity

Monotonicity in a function refers to the consistent behavior of the function in terms of increasing or decreasing. A function that is always increasing never decreases as its input increases. This property is usually confirmed using the first derivative, where a positive derivative over the entire domain indicates that the function is monotone increasing.

Graph Sketching

Graph sketching involves drawing the graph of a function by analyzing its key characteristics—such as monotonicity, concavity, inflection points, and intercepts. By combining the information about where the function is increasing and its concavity behavior, one can produce an approximate visual representation that captures the essential behavior and shape of the function.
