Find the Domain y=2x-4

Problem

y=2*x−4

Solution

1. Identify the type of function. The given equation y=2*x−4 is a linear function, which is a specific type of polynomial function.

2. Determine if there are any restrictions. Polynomial functions do not have denominators containing variables (which could lead to division by zero) or even-indexed roots (which could lead to imaginary numbers).

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

Final Answer

Domain: *(−∞,∞)
