Find the Domain y=-4-3x

Problem

y=−4−3*x

Solution

1. Identify the type of function provided. The equation y=−4−3*x is a linear function, which is a specific type of polynomial 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 even-indexed roots (like square roots) that could contain negative values.

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

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

Final Answer

Domain: *(−∞,∞)
