Find the Domain y=-2x^2

Problem

y=−2*x2

Solution

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

2. Determine if there are any restrictions on the input variable x Polynomials do not contain square roots of negative numbers, logarithms of non-positive numbers, or divisions by zero.

3. Conclude that since there are no mathematical operations that restrict the input, the function is defined for all real numbers.

4. Express the domain in interval notation or set-builder notation.

Final Answer

Domain: *(−∞,∞)
