Q: Find zero/s of a function below. Write a step-by-step solution using Math Window ƒ(x) = =x²-x-12

A:

Domain

In simple mathematics terms, a domain is defined as the space on which all the possible inputs for the function will lie. It can also be expressed as a set of departures for the required function.
