Find the Domain 7x+3x^7y

Problem

7*x+3*x7*y

Solution

1. Identify the type of expression provided. The expression 7*x+3*x7*y is a polynomial function of two variables, x and y

2. Determine if there are any restrictions on the variables. Restrictions typically occur with denominators (which cannot be zero), even roots (where the radicand must be non-negative), or logarithms (where the argument must be positive).

3. Observe that this expression contains only addition and multiplication of variables with positive integer exponents.

4. Conclude that the expression is defined for all real values of x and y

Final Answer

Domain={(x,y)∈ℝ2}
