1. You Down Wit HPC?! Yeah, You Know Me! Welcome Back!

2. 1.1/1.2/A.3: Rectangular Coordinates/Graphing Equations/Factoring The students (YOU!), will be able to: Use the distance and midpoint formulas Transfer algebraic information into graphic information Determine x-and y-intercepts COMPLETELY factor polynomials Solve applications problems

3. 1.1/1.2/A.3: Rectangular Coordinates/Graphing Equations/Factoring Remember these?

4. 1.1/1.2/A.3: Rectangular Coordinates/Graphing Equations/Factoring Ex1: Consider the 3 points T = (-2,1), S = (2,3) and G = (3,1). Plot each point and form the triangle TSG. Find the length of each side of the triangle. Verify that the triangle is a right triangle. Find the midpoint of TG. Find the area of the triangle.

5. 1.1/1.2/A.3: Rectangular Coordinates/Graphing Equations/Factoring Ex2: Given the equation f(x) = (x – 1) 2 – 9. Determine whether (3,5) is on the graph. If (1,b) is on the graph, what is b? Algebraically determine the x- and y-intercepts. Graph f(x) on a GC and then determine the intercepts.

6. 1.1/1.2/A.3: Rectangular Coordinates/Graphing Equations/Factoring Ex3: Factor COMPLETELY! Factoring is _________! x 3 + 27 x 4 – 1 9x 2 – 12x + 4 x 3 – 4x 2 + 2x - 8

7. 1.1/1.2/A.3: Rectangular Coordinates/Graphing Equations/Factoring For tomorrow: Do your best on HW#1 Read through syllabus, Learning Log Sheet. What are your expectations for this class? I need your best effort each day. I know I will bring it! You Down Wit HPC?!...
