**range**of a set of data is the difference between the highest and lowest values in the set. To find the

**range**, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

Likewise, how find the range of a function?

**Overall, the steps for algebraically finding the range of a function are:**

- Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
- Find the domain of g(y), and this will be the range of f(x).
- If you can't seem to solve for x, then try graphing the function to find the range.

One may also ask, how do you find the domain and range of a function? **Example 1:**

- Find the domain and range of the function y=1x+3−5 .
- To find the excluded value in the domain of the function, equate the denominator to zero and solve for x .
- x+3=0⇒x=−3.
- So, the domain of the function is set of real numbers except −3 .
- Interchange the x and y .
- x=1y+3−5.
- Solving for y you get,

Additionally, how do you find the range of a domain?

Because the **domain** refers to the set of possible input values, the **domain** of a graph consists of all the input values shown on the x-axis. The **range** is the set of possible output values, which are shown on the y-axis.

What is a function in algebra?

A **function** is an equation that has only one answer for y for every x. A **function** assigns exactly one output to each input of a specified type. It is common to name a **function** either f(x) or g(x) instead of y. f(2) means that we should find the value of our **function** when x equals 2. Example.
