The range is the set of all possible output values (y-values) that a function can have. To find the range, follow these steps:
1. Determine the domain of the function, which is the set of all possible input values (x-values).
2. Determine the equation or rule for the function.
3. Plug in the minimum and maximum values of the domain into the function to find the corresponding minimum and maximum values of the range.
4. Write the range as a set of numbers or an interval if it is continuous.
Note: If the function is not given explicitly, you may need to plot the function and observe the highest and lowest points to find the range.
