Find domain and range of a function algebraically.

Find domain and range from graphs another way to identify the domain and range of functions is by using graphs. The function equation may be quadratic a fraction or contain roots. Learning how to find the domain of a function is a crucial skill in algebra because it gives you the capability to assess where a function is properly defined. The task of finding where it is valid to operate a function is a useful one.

The domain of the function is all of the x values horizontal axis that will give you a valid y value output.

The range is the set of possible output values which are shown on the y axis. F x 2x 2 3x 4. To calculate the domain of the function you must first evaluate the terms within the equation. Or in other words the region where it is valid to operate the function.
