(8) Quadratic and square root functions. The student formulates equations and inequalities based on quadratic functions, uses a variety of methods to solve them, and analyzes the solutions in terms of the situation. The student is expected to:

• (A) analyze situations involving quadratic functions and formulate quadratic equations or inequalities to solve problems;

• (B) analyze and interpret the solutions of quadratic equations using discriminants and solve quadratic equations using the quadratic formula;

• (C) compare and translate between algebraic and graphical solutions of quadratic equations; and

• (D) solve quadratic equations and inequalities using graphs, tables, and algebraic methods.
