Find the Domain (x+4)(x-4)
Problem
Solution
Identify the type of function. The expression
(x+4)*(x−4) is a polynomial function (specifically a quadratic function).Determine if there are any restrictions. Polynomials do not contain divisions by zero, square roots of negative numbers, or logarithms of non-positive numbers.
Conclude the domain. Since there are no values of
x that make the expression undefined, the function is defined for all real numbers.
