Find the Domain x^2-5x-4

Problem

x2−5*x−4

Solution

1. Identify the type of function given. The expression x2−5*x−4 is a polynomial function of degree 2.

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

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

4. Express the domain in interval notation, which represents the set of all real numbers from negative infinity to positive infinity.

Final Answer

Domain:(−∞,∞)
