Locate the Solution(s) on a Graph of Two Functions: The graph below was generated by sketching functions from the equation . The blue graph is the function  and represents the left side of the equation. The red graph is the function  and represents the right side of the equation. Which points (A, B, C, D) on the graph represent solutions to the equation? Select all that are solutions.

Continue Solving: After both sides of the equation are squared, the next step is to collect all terms on one side of the equation. Which of the following is the equation that results when all terms have been collected on one side?

Identify the Basic Graph: The algebraic expression on the left side of the equation represents a function. What is the shape of the graph of the function ?
