Answer:

Solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain.

Step-by-step explanation:

To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

Hope this helps you !! :)

Answer:

The domain is the "x" in the function and the range is the "y" in it.

Example:

Name all of the domain and ranges of the following functions:

{(2, 9), (3, 5), (5, 4), (7, 1), (9, 3)}

Domains: 2, 3, 5, 7, 9

Ranges: 9, 5, 4, 1, 3

Step-by-step explanation:

In the example, we can see that all of the x's resemble the domain and all of the y's resemble the ranges.

It's important to know that if the domains repeat themselves or if the ranges repeat themselves, you only put the number once.

I hope this helps. Let me know if you need another example!
