Find the Domain 7x+15y

Problem

7*x+15*y

Solution

1. Identify the type of expression provided. The expression 7*x+15*y is a linear polynomial in two variables, x and y

2. Determine if there are any restrictions on the variables. Restrictions typically occur with divisions by zero, square roots of negative numbers, or logarithms of non-positive numbers.

3. Analyze the operations involved. Since the expression only involves multiplication and addition of real numbers, it is defined for all real values of x and y

4. State the domain in terms of the set of all possible ordered pairs (x,y)

Final Answer

Domain={(x,y)|x∈ℝ,y∈ℝ}
