Skill builder topic 1.3 estimating limit values from graphs

In mathematics, a limit is a value that a function approaches as the input approaches some value. Limits can be used to describe the behavior of functions at specific points, such as when the input is very large or very small.

Graphs can be used to visualize limits and to estimate their values.

There are different types of limits. One type of limit is a one-sided limit. A one-sided limit describes the behavior of a function as the input approaches a value from one side. For example, the one-sided limit of the function f(x) = x2as xapproaches 0 from the left is 0. This means that as xgets closer and closer to 0 from the negative side, the value of f(x)gets closer and closer to 0.

Another type of limit is a two-sided limit. A two-sided limit describes the behavior of a function as the input approaches a value from both sides. For example, the two-sided limit of the function f(x) = x2as xapproaches 0 is 0. This means that as xgets closer and closer to 0 from both the positive and negative sides, the value of f(x)gets closer and closer to 0.

There are two main methods for estimating limit values from graphs: zooming in and using tables.

Zooming inis a method for estimating limit values by making the graph larger and larger. As the graph gets larger, the points on the graph get closer and closer together, and the limit value becomes more and more apparent. For example, the graph of the function f(x) = x2as xapproaches 0 is shown below.

Graph of f(x) = x^2 as x approaches 0

As the graph is zoomed in, the points on the graph get closer and closer together, and the limit value of 0 becomes more and more apparent.

Using tablesis another method for estimating limit values from graphs. To use this method, create a table of values for the function at values of xthat are close to the limit value. For example, the table below shows the values of f(x) = x2for values of xthat are close to 0.

x f(x)
-0.1 0.01
-0.01 0.0001
0.01 0.0001
0.1 0.01

As the values of xin the table get closer and closer to 0, the values of f(x)get closer and closer to 0. This suggests that the limit of f(x)as xapproaches 0 is 0.

Q&A
