Key Concepts

Continuity of Functions

A function is continuous at a point if the limit of the function as it approaches that point equals the function's value at that point. For a function to be continuous over an interval, it must be continuous at every point within that interval. Understanding continuity is essential for analyzing the behavior of the parking cost function over the specified range.

Intervals of Continuity

Intervals of continuity refer to the ranges of input values for which a function remains continuous. To determine these intervals, one must identify points where the function may be undefined or exhibit discontinuities, such as jumps, holes, or vertical asymptotes. This analysis helps in understanding where the parking cost function behaves predictably.

Piecewise Functions

A piecewise function is defined by different expressions based on the input value. In the context of the parking cost function, it may have different rates or rules for different time intervals. Recognizing how piecewise definitions affect continuity is crucial for accurately determining the intervals of continuity for the function.
