Find the Domain f(x)=x^2

Problem

ƒ(x)=x2

Solution

1. Identify the type of function. The function ƒ(x)=x2 is a polynomial function.

2. Determine if there are any restrictions on the input 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.

3. Conclude that the input x can be any real number from negative infinity to positive infinity.

Final Answer

Domain: *(−∞,∞)
