This math topic involves analyzing quadratic discriminants to determine if quadratic functions have real roots. The focus is on interpreting graphs and using the discriminant from the quadratic formula to verify the nature of the roots. Each question provides a graph of a quadratic function, and the problem is to decide whether the function has one or more real roots. The responses are structured as a binary choice between "Yes" (it has real roots) or "No" (it does not). The worksheet is an introductory level practice on quadratic discriminants.
