Find the Domain y=x-9/5

Problem

y=x−9/5

Solution

1. Identify the type of function provided. The expression y=x−9/5 is a linear function, which is a specific type of polynomial function.

2. Determine if there are any restrictions on the variable x Restrictions typically occur in cases involving division by zero (rational functions) or taking the square root of a negative number (radical functions).

3. Observe that there are no variables in the denominator and no radical signs in the expression.

4. Conclude that the function is defined for all real numbers because any real value substituted for x will result in a valid real value for y

Final Answer

Domain: *(−∞,∞)
