Find the Domain y=-5x

Problem

y=−5*x

Solution

1. Identify the type of function. The given equation y=−5*x 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 like division by zero, square roots of negative numbers, or logarithms of non-positive numbers.

3. Analyze the expression −5*x Since any real number x can be multiplied by −5 to produce a real number y there are no restrictions on the input.

4. State the domain in interval notation. Since all real numbers are valid inputs, the domain extends from negative infinity to positive infinity.

Final Answer

Domain: *(−∞,∞)
