U7D15 Have out: Bellwork: Pencil, red pen, highlighter, notebook Determine all the zeros and sketch the graph of y = P(x). Label all intercepts! (Hint: Use the Rational Root Theorem and synthetic division) P(x) = x3 – 3x + 2 +1 +1 factors of 2 ±1, ±2 ±1, ±2 factors of 1 ±1 total:

☺ ±1, ±2 P(x) = x3 + 0x2 – 3x + 2 1 –3 2 try: x = 1 1 1 –2 1 1 1 –2 –2 +1 1 –3 2 +1 try: x = 1 1 1 –2 +1 1 1 ☺ 1 –2 +1 –2 P(x) = (x – 1)(x2 + x – 2) 2 –1 1 P(x) = (x – 1)(x – 1)(x + 2) +1 factor 0 = (x – 1)(x – 1)(x + 2) +1 equal to 0 x – 1 = 0 or x + 2 = 0 +1 ZPP x = 1 +1 x = –2 +1 (double zero)

P(x) = (x – 1)(x – 1)(x + 2) y P(x) zeros: x = 1, 1, –2 double zero x (0, 2) double zero (–2, 0) +1 labeled x–intercepts x (1, 0) +1 labeled y–intercept +1 end behavior +1 overall graph total:

Clear your desk except for a red pen and your study team test. Its time to GRADE the… Study Team Test! Clear your desk except for a red pen and your study team test.

Unit 7 Test Bring: Pencils, erasers, highlighter, ruler, 3x5 notecard, non–graphing calculator 3x5 notecard: Worth 5 assignment points. Must be turned in with the exam You may use a NON–GRAPHING calculator on the test. This also means that you must give the exact and approximate answers for all questions. Study your notes and worksheets. If you know you take a long time on tests, then get to class quickly to begin. This may be a LONG TEST!!! You will not be allowed to have extra time during lunch or after school.
