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.

What is the domain of the function discussed in the text?

Explain why the values that make the denominator equal to zero are important.

What are the specific values that X cannot equal according to the text?

Describe the intervals of the function as mentioned in the text.

How would you express the domain in interval notation based on the information provided?
