Welcome to quadratics! Section 9.1

• Read example A carefully, understand it!
• read the paragraph after the example
• do the investigation. Understand this, it is important! Remember what you learned in chapter 7, h(t) does not mean height multiplied by time, it means height as a property of time, h of t.
• read remainder of chapter introduction. Make sure you understand the terms: general form, radical expressions, irrational numbers, real numbers
• Understand example B, this is how we will solve a quadratic when it is in vertex form, very important!
• Practice problems: 1 (graph on the calculator, make 2 graphs and find the intersection, just like you did in chapter 6), 2, 3 (solve like you learned in example B), 4 (think about what you learned in problem 1), 5, 6
