Problem

y=25*x2−1

Solution

1. Identify the type of function provided. The expression 25*x2−1 is a polynomial function, specifically a quadratic.

2. Determine if there are any restrictions on the input variable x Polynomials do not contain denominators that could be zero or square roots of negative numbers.

3. Conclude that the function is defined for all real numbers because there are no values of x that would result in an undefined expression.

Final Answer

Domain: *(−∞,∞)
