Find the Domain y=57-142

Problem

y=57−142

Solution

1. Simplify the expression by performing the subtraction.

y=−85

2. Identify the type of function. This is a constant function, which is a specific type of polynomial function.

3. Determine the domain. Polynomial functions are defined for all real numbers because there are no denominators that could be zero and no even roots of negative numbers.

4. Express the domain in interval notation. Since the function is defined for every possible value of x the domain is all real numbers.

(−∞,∞)

Final Answer

Domain of *y=57−142* is *(−∞,∞)
