How do you find the domain and range of a function in precalculus?
Answer 1
Carolyn Houston
To find the domain of a function, determine all possible input values (x-values) that do not cause division by zero or other undefined operations. The range is the set of all possible output values (y-values) that result from using the domain values. Analyze the function’s behavior, considering restrictions like square roots, logarithms, and rational expressions.
