Find the Domain -x^3-8x^2-19x-12

Problem

ƒ(x)=−x3−8*x2−19*x−12

Solution

1. Identify the type of function. The expression −x3−8*x2−19*x−12 is a polynomial function.

2. Determine the restrictions. Polynomial functions do not contain any operations that restrict the input, such as division by zero or taking the square root of a negative number.

3. Conclude the domain. Since the function is defined for all real numbers, the domain is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
