Problem

x3−2*x+1

Solution

1. Identify the type of function provided. The expression x3−2*x+1 is a polynomial function.

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

3. Conclude that since there are no values of x that make the expression undefined, the function is defined for all real numbers.

4. Express the domain in interval notation.

Final Answer

Domain: *(−∞,∞)
