Find the Domain y=-2x^2+bx+5

Problem

y=−2*x2+b*x+5

Solution

1. Identify the type of function. The given equation y=−2*x2+b*x+5 is a polynomial function, specifically a quadratic function.

2. Determine if there are any restrictions. Polynomial functions are defined for all real numbers because there are no denominators that could be zero and no even-indexed roots of negative numbers.

3. State the domain. Since there are no values of x that make the expression undefined, the domain consists of all real numbers.

Final Answer

Domain: *(−∞,∞)
