If a function is present in one of the functions mentioned in the above rules, we can straight away apply the rules and find its range. Otherwise, we can graph it and look at the y-values the graph covers to calculate range. Here are some examples: Example 1:To calculate the range of...
How do I find the domain and range of a function? Given a function, the domain and range can be found by analyzing the function itself or by looking at its graph. All x-values that can be input are included in the domain and all y-values that are output can be included in the ran...

In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful...
Find the domain and range of the functionf(x)=x+2x2−9,\displaystyle f{{\left({x}\right)}}=\frac{\sqrt{{{x}+{2}}}{{{x}^{2}-{9}}},f(x)=x2−9x+2,without using a graph. Solution In the numerator (top) of this fraction, we have a square root. To make su...
Now that you've learned the basics on how to find the domain and range of a graph, try out these practice problems! Question 1: State the domain, range, and whether it is a function Domain and range of a function (Q1) Solution: ...
Domain and Range of a Function - Domain of a Function| Range of a Function. Co-domain of a Function | Difference Between Domain & Codomain of a Function and Solved examples.
A horizontal asymptote (HA) of a function is an imaginary horizontal line to which its graph appears to be very close but never touch. It is of the form y = some number. Here, "some number" is closely connected to the excluded values from the range. A rational function can have at ...
The domain of this function is all real numbers. In fact, the domain of all quadratic functions is all real numbers! How to Find the Range of a Quadratic Function Now for the range. We’ll use a similar approach, but now we are only concerned with what the graph looks like vertically...
