Find the Domain 3x-y=-20

Problem

3*x−y=−20

Solution

1. Identify the type of equation provided. The equation 3*x−y=−20 is a linear equation in two variables, which represents a straight line in the Cartesian plane.

2. Solve for y to express the equation in slope-intercept form.

y=3*x+20

3. Analyze the function for any restrictions. In the expression 3*x+20 there are no denominators containing variables, no square roots of negative numbers, and no logarithms.

4. Determine the domain. Since the expression is defined for every real number x the domain consists of all real numbers.

Final Answer

Domain:(−∞,∞)
