Find the Domain f(x)=-4x-7

Problem

ƒ(x)=−4*x−7

Solution

1. Identify the type of function provided. The function ƒ(x)=−4*x−7 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 have negative radicands.

3. Conclude that the function is defined for all real numbers. In interval notation, this is represented as (−∞,∞)

Final Answer

Domain: *(−∞,∞)
