Find the Domain y=5x

Problem

y=5*x

Solution

1. Identify the type of function provided. The expression y=5*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 square roots of negative numbers to consider.

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

Final Answer

Domain: *(−∞,∞)
