Assume that each function is continuous. Do not use a graphing calculator.
On the same coordinate axes, sketch the graphs of a constant function $f$ and a nonlinear function $g$ that intersect exactly twice.

Key Concepts

Intersection of Graphs

The intersection of graphs refers to the points where the outputs of two functions are equal, meaning their graphs cross each other. Analyzing intersections is critical in problem-solving, as these points often represent solutions to equations or critical values in application contexts. Understanding how and why graphs intersect allows for deeper insights into the relationships between different functions.

Nonlinear Function

A nonlinear function is any function that does not produce a straight-line graph; its rate of change is not constant. Such functions can have curves, peaks, or valleys, and they typically allow for more varied behavior such as multiple intersections with a constant or straight-line graph, making them important for understanding complex dynamics in mathematics.

Constant Function

A constant function is one that produces the same output regardless of the input value, resulting in a horizontal line when graphed. This simplicity makes constant functions useful as a baseline or reference when comparing with more complex functions, as the constant value provides a straightforward comparison point for intersections.

Continuous Functions

A continuous function is one where the graph can be drawn without lifting the pencil, meaning there are no breaks, jumps, or holes in the graph. Continuity ensures that the function behaves predictably, and small changes in the input yield small changes in the output, which is a key property when analyzing intersections and behavior of functions.
