Find the Domain f(k)=-k^2-3k+1

Problem

ƒ(k)=−k2−3*k+1

Solution

1. Identify the type of function. The given expression ƒ(k)=−k2−3*k+1 is a polynomial function of degree 2 (a quadratic function).

2. Check for restrictions. Polynomial functions do not contain any operations that restrict the input values, such as division by zero (fractions with variables in the denominator) or square roots of negative numbers.

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

Final Answer

Domain: *(−∞,∞)
