Find the Domain y=15x-5

Problem

y=15*x−5

Solution

1. Identify the type of function. The given equation y=15*x−5 is a linear function, which is a specific type of polynomial function.

2. Determine if there are any restrictions. For a function to have a restricted domain, there must be operations that are undefined for certain values of x such as division by zero or taking the square root of a negative number.

3. Analyze the expression. In the expression 15*x−5 any real number can be multiplied by 15 and then have 5 subtracted from it without resulting in an undefined value.

4. Conclude the domain. Since there are no restrictions, the domain consists of all real numbers.

Final Answer

Domain: *(−∞,∞)
