Find the Domain f(x)=5x^2+2x-1

Problem

ƒ(x)=5*x2+2*x−1

Solution

1. Identify the type of function. The given expression ƒ(x)=5*x2+2*x−1 is a polynomial function of degree 2.

2. Determine if there are any restrictions. Polynomial functions do not contain square roots of negative numbers, divisions by zero, or logarithms of non-positive numbers.

3. Conclude the domain. Since there are no values of x that make the expression undefined, the function is defined for all real numbers.

Final Answer

Domain: *(−∞,∞)
