Students should note that the solutions they find algebraically are the places where the graph crosses the x axis. 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. Students trace to find the roots of the function and solve the inequality by inspection of the graph. The student formulates equations and inequalities based on square root functions, uses a variety of methods to solve them, and analyzes the solutions in terms of the situation.
