This topic focuses on understanding and determining the quadratic discriminant, represented by the symbol \(\Delta\). It practices identifying if \(\Delta\) is greater than, less than, or equal to zero based on given quadratic functions. This skill is vital for students as it helps predict the nature of the roots of quadratic equations—whether they have two real solutions, one real solution, or no real solutions. The questions present quadratic functions and require students to analyze their graphs or equations to determine the value of \(\Delta\). This is part of an introductory unit on the quadratic formula and discriminants.
