Find the Domain f(x)=9x+7

Problem

ƒ(x)=9*x+7

Solution

1. Identify the type of function. The given function ƒ(x)=9*x+7 is a linear polynomial function.

2. Analyze the expression for restrictions. A function's domain is restricted by operations such as division by zero or taking the square root of a negative number.

3. Determine if any restrictions exist. Since there are no denominators containing variables and no radicals with even indices, the function is defined for all real numbers.

4. State the domain in interval notation. The set of all real numbers is represented as (−∞,∞)

Final Answer

Domain: *(−∞,∞)
