Find the Domain y=x^2+2x

Problem

y=x2+2*x

Solution

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

2. Determine if there are any restrictions. Polynomials do not have denominators that could be zero or square roots of negative numbers.

3. Conclude the domain. Since the function is defined for all real numbers, the domain includes every value of x from negative infinity to positive infinity.

Final Answer

Domain: *(−∞,∞)
