Q. What is the domain of this quadratic function?y=x2−4x+3Choices:(A){x∣x≥−1}(B){x∣x≥2}(C){x∣x≤2}(D)all real numbers
Define Function Domain: The domain of a function is the set of all possible input values (x-values) for which the function is defined. For a quadratic function, which is a polynomial function, the domain is typically all real numbers because you can plug any real number into a quadratic equation and get a real number out.
Check Restrictions: To confirm the domain for the quadratic function y=x2−4x+3, we need to check if there are any restrictions on the x-values. Since there are no square roots, logarithms, or denominators that could potentially restrict the domain, we can conclude that the domain is all real numbers.
