Find the Domain y=7x-2

Problem

y=7*x−2

Solution

1. Identify the type of function. The given equation y=7*x−2 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 potential mathematical errors such as division by zero (fractions) or taking the square root of a negative number (radicals).

3. Analyze the expression 7*x−2 Since there are no denominators containing variables and no even-indexed roots, any real number can be substituted for x

4. Conclude the domain. The domain of any polynomial function is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
