Understanding Step Graphs and Functions

The video tutorial explores the concept of non-linear relationships using parking fees as an example. It explains how these fees can be represented on a graph, introducing the idea of step graphs. The tutorial further discusses the characteristics of step graphs, highlighting the presence of discontinuities and how they can be represented using specific notations.

What is an example of a real-life situation where values do not follow a linear relationship?

• The cost of parking based on duration

• The distance traveled over time at constant speed

• The temperature change over a day

• The growth of a plant over time

How does a step graph represent parking charges?

• As a circular pattern

• As a smooth curve

• As a single straight line

• As a series of steps

What happens to the parking charge after three hours and one minute?

• It resets to zero

• It decreases

• It remains the same

• It increases to a new level

Why might step graphs be considered linear?

• They have a smooth curve

• They consist of straight lines

• They have no discontinuities

• They form a circular pattern

What is a discontinuity in a graph?

• A gap or jump in the graph

• A circular loop

• A constant slope

• A smooth transition

How can the ambiguity in step graphs be resolved?

• By drawing arrows

• By using circles to indicate boundaries

• By adding labels

• By using different colors

What does a filled circle in a step graph indicate?

• The end of a step

• A point where the value is taken

• The start of a new step

• A point of discontinuity

What is the main characteristic of a step function?

• It forms a circular pattern

• It consists of flat segments

• It has a constant slope

• It is a continuous curve

Why is it important to resolve ambiguities in step graphs?

• To simplify the graph

• To add more data points

• To ensure accurate interpretation of values

• To make the graph look better

What is the broad classification of step graphs?

• Non-linear relationships

• Exponential relationships

• Circular relationships

• Linear relationships
