Find the Domain x^3-9

Problem

x3−9

Solution

1. Identify the type of function. The expression x3−9 is a polynomial function.

2. Determine if there are any restrictions. Polynomials do not contain denominators with variables, square roots of negative numbers, or logarithms.

3. Conclude the domain. Since there are no values of x that make the expression undefined, the domain consists of all real numbers.

Final Answer

Domain:(−∞,∞)
