Find the Domain 3x-5y=15

Problem

3*x−5*y=15

Solution

1. Identify the type of equation provided. The equation 3*x−5*y=15 is a linear equation in two variables, which represents a straight line in the Cartesian plane.

2. Solve for y in terms of x to express the relation as a function.

−5*y=−3*x+15

y=3/5*x−3

3. Analyze the resulting function ƒ(x)=3/5*x−3 Since this is a polynomial function (specifically a linear function), there are no values of x that would result in division by zero or the square root of a negative number.

4. Determine the domain. Because the function is defined for all real numbers, the domain consists of all values from negative infinity to positive infinity.

Final Answer

Domain: *(−∞,∞)
