Find the Domain y=-9/10x+18

Problem

y=−9/10*x+18

Solution

1. Identify the type of function. The given equation y=−9/10*x+18 is a linear function, which is a specific type of polynomial function.

2. Determine potential restrictions. For a function's domain to be restricted, there must be operations such as division by zero (fractions with variables in the denominator), square roots of negative numbers, or logarithms of non-positive numbers.

3. Analyze the expression. Since there are no denominators containing x no radicals, and no logarithms, the variable x can take any real number value.

4. State the domain. The domain of any linear function (that is not a vertical line) is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
