Find the Domain y=x^2*(2x)+15

Problem

y=x^2*(2*x)+15

Solution

1. Simplify the expression by multiplying the terms to see the function's form.

y=2*x^3+15

2. Identify the type of function. This is a polynomial function of degree 3.

3. Determine the constraints on the variable x Polynomials are defined for all real numbers because there are no denominators that could be zero and no even-indexed roots of negative numbers.

4. State the domain in interval notation. Since there are no restrictions, the domain is all real numbers.

(−∞,∞)

Final Answer

Domain:(−∞,∞)
