What Is the Range of a Function

What Is the Range of a Function

The range of a function is the complete set of all possible resulting values of the dependent variable, after you substitute the domain. In other words, the range is the resulting y-values you get after substituting all the possible x-values.

For example, for y = sqrt(x + 2), the range of this function is y >= 0.
