Find the Domain (4+9y)/7=7

Problem

(4+9*y)/7=7

Solution

1. Identify the type of expression given. The expression is a linear equation in terms of the variable y

2. Analyze the expression for potential restrictions. In mathematics, domain restrictions typically occur when there is a denominator containing a variable (which cannot be zero) or an even root containing a variable (the radicand must be non-negative).

3. Check the denominator. The denominator in this expression is the constant 7 which is never zero.

4. Determine the domain. Since there are no variables in the denominator and no roots or logarithms, the variable y can take any real number value.

Final Answer

Domain: *(−∞,∞)
