Find the Domain -4x^2-32x-28

Problem

ƒ(x)=−4*x2−32*x−28

Solution

1. Identify the type of function provided. The expression −4*x2−32*x−28 is a polynomial function of degree 2, also known as a quadratic function.

2. Determine if there are any restrictions on the input variable x For polynomial functions, there are no denominators that could be zero and no square roots of negative numbers to consider.

3. Conclude that the function is defined for all real numbers because any real value substituted for x will result in a defined real number.

Final Answer

Domain: *(−∞,∞)
