Find the Domain 7x^3-21x^2-91x+104

Problem

7*x3−21*x2−91*x+104

Solution

1. Identify the type of function provided. The expression 7*x3−21*x2−91*x+104 is a polynomial function.

2. Determine the restrictions for the domain. Polynomials do not contain variables in denominators, under even roots, or within logarithms.

3. Apply the definition of a polynomial domain. Since there are no values of x that would make the expression undefined, the function is defined for all real numbers.

4. State the domain in interval notation. The set of all real numbers is represented as (−∞,∞)

Final Answer

Domain: *(−∞,∞)
