# How do you find the range of a point?

Summary: The 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:

1. Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
2. Find the domain of g(y), and this will be the range of f(x).
3. 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:

1. Find the domain and range of the function y=1x+3−5 .
2. To find the excluded value in the domain of the function, equate the denominator to zero and solve for x .
3. x+3=0⇒x=−3.
4. So, the domain of the function is set of real numbers except −3 .
5. Interchange the x and y .
6. x=1y+3−5.
7. 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.
