What are examples of using graphs to help solve word problems?
Here is a simple example of a word problem where graph helps.
Solution
In this and many other cases the graph might not provide an exact solution, but it helps a lot to understand the reality behind a problem. Moreover, graphical representation of a problem would help to find a precise analytical approach to exact solution. In the example above this process of intersecting two graphs gives a strong hint to an equation used to algebraically solve the problem.

Examples of using graphs to help solve word problems include:

Distancetime graphs: Representing the relationship between distance traveled and time elapsed for scenarios like motion of vehicles or objects.

Supply and demand graphs: Illustrating the relationship between the quantity of a product supplied or demanded and its price, commonly used in economics.

Bar graphs and pie charts: Visualizing data to compare different categories or proportions, such as sales figures, population demographics, or survey results.

Line graphs for trends: Showing trends over time, like changes in temperature, stock prices, or population growth.

Histograms for distribution: Displaying frequency distributions of data, useful for analyzing statistical data sets such as test scores or survey responses.

Function graphs: Depicting mathematical functions to understand their behavior and relationships between variables, like profit functions or growth models.

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
