Solution (Using Factoring): - Factor: \( (x - 2)(x - 3) = 0 \) - Set each factor equal to zero: - \( x - 2 = 0 \Rightarrow x = 2 \) - \( x - 3 = 0 \Rightarrow x = 3 \) Answer: - \( x = 2 \) or \( x = 3 \) Answer Key Reference: The answer key confirms these solutions and may provide additional methods, such as completing the square or quadratic formula, for comprehensive understanding. --- Graphing Quadratic Functions Graphing involves plotting the parabola and identifying key features: - Vertex - Axis of symmetry - Intercepts Sample Problem: Graph \( y = x^2 + 4x + 3 \). Solution: - Convert to vertex form: \( y = (x + 2)^2 - 1 \) - Vertex: \( (-2, -1) \) - Axis of symmetry: \( x = -2 \) - Intercepts: - \( y \)- intercept at \( (0, 3) \) - \( x \)-intercepts at solutions to \( (x + 2)^2 - 1 = 0 \) Answer: The graph is a parabola opening upward with vertex at \( (-2, -1) \), crossing the y-axis at 3, and x-intercepts at \( -3 \) and \( -1 \). Answer Key Reference: The answer key provides detailed graphing steps, including plotting points and confirming the vertex. --- Word Problems and Applications Applying quadratic functions to real-world scenarios is vital. Sample Problem: A ball is thrown upward from a height of 5 meters with an initial velocity. The height after \( t \) seconds is modeled by \( h(t) = -4.9t^2 + 9.8t + 5 \). When does the ball hit the ground? Solution: - Set \( h(t) = 0 \): \( -4.9t^2 + 9.8t + 5 = 0 \) - Use quadratic formula: \( t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \) Where \( a = -4.9 \), \( b = 9.8 \), \( c = 5 \) - Calculate discriminant: \( \Delta = 9.8^2 - 4 \times (-4.9) \times 5 = 96.04 + 98 = 194.04 \) - Find roots: \( t = \frac{-9.8 \pm \sqrt{194.04}}{2 \times -4.9} \) \( t = \frac{-9.8 \pm 13.928}{-9.8} \) - Positive root: \( t = \frac{-9.8 + 13.928}{-9.8} = \frac{4.128}{-9.8} \approx -0.421 \) (discard, since negative time) - Negative root: \( t = \frac{-9.8 - 13.928}{-9.8} = \frac{-23.728}{-9.8} \approx 2.422 \) Answer: The ball hits the ground approximately 2.42 seconds after being thrown. Answer Key Reference: The answer key confirms the quadratic formula application and provides approximate solutions, emphasizing the importance of discriminant calculation. --- Accessing and Using the Chapter 6 Answer Key Methods to Obtain the Answer Key - Teacher Resources: Many teachers have access through school accounts or teacher editions. - Student Workbooks: Some workbooks include answer keys at the back. - Online Platforms: Websites associated with McGraw Hill often provide digital answer keys for registered users. - Educational Websites: Third-party sites may offer solutions, but ensure they are accurate and aligned with the textbook.
