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

2. ☺ ±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 = or x + 2 = 0
+1 ZPP
x = 1 +1
x = –2 +1
(double zero)

3. 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

4. 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.

5. 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.
