Multiplying a function by a multiple, then determine the domain

The video tutorial explains a mathematical function, simplifying it to -, 4 / X^2 + X. It discusses the domain, noting that it includes all real numbers except those that make the denominator zero, specifically -, 1 and 0. The domain is then expressed in interval notation as negative infinity to -, 1, -, 1 to 0, and 0 to infinity.
