How do you find the range for a function equation?

To find the range of a function, you first need to identify the set of all possible output values (y-values) corresponding to the inputs (x-values). For many functions, you can analyze the function's behavior by examining its critical points, asymptotes, and intercepts. Additionally, you can use techniques like substitution, solving for y, or graphing the function to visually interpret the range. Ultimately, the range is the collection of all y-values that the function can produce.
