Find the Domain f(x)x^2-3x-12

Problem

ƒ(x)=x2−3*x−12

Solution

1. Identify the type of function. The given function ƒ(x)=x2−3*x−12 is a polynomial function of degree 2.

2. Determine any restrictions on the variable x Polynomial functions do not contain square roots of negative numbers, divisions by zero, or logarithms of non-positive numbers.

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

Final Answer

Domain of *ƒ(x)=(−∞,∞)
