Find the Domain y=9x+3

Problem

y=9*x+3

Solution

1. Identify the type of function. The given equation y=9*x+3 is a linear function, which is a specific type of polynomial function.

2. Determine any restrictions on the input variable x For polynomial functions, there are no values of x that would result in division by zero or the square root of a negative number.

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

Final Answer

Domain: *(−∞,∞)
