  1. Solve the following quadratic equation by factoring. EOCT Review x2  - x - 72 = 0 • x = -9 or 9 b) x = -8 or 9 • c) x = 36 or -2 d) x = -36 or 2 b

  2. Solve the following quadratic equation by factoring. X2 – 20x + 51 = 0 EOCT Review b • x = -3 or -17 b) x = 3 or 17 • c) X = 4 or 5 d) not factorable

  3. EOCT Review • If Fred cannot swin, then he is not Kay's brother. • If Dave can swim, then he is not Kay's brother. • If Pete is Kay's brother, then he cannot swim. • If Mark is not Kay's brother, then he cannot swim. a

  4. 3.1 Even and Odd Functions (algebraically) A function is even if f(-x) = f(x) If you plug in -x and get the original function, then it’s even. A function is odd if f(-x) = -f(x) If you plug in -x and get the opposite function, then it’s odd.

  5. Even, Odd or Neither? Ex. 1 Graphically Algebraically EVEN

  6. Even, Odd or Neither? Ex. 2 Graphically Algebraically ODD

  7. Ex. 3 Even, Odd or Neither? Graphically Algebraically EVEN

  8. Ex. 4 Even, Odd or Neither? Graphically Algebraically Neither

  9. Even, Odd or Neither? EVEN ODD

  10. What do you notice about the graphs of even functions? Even functions are symmetric about the y-axis

  11. What do you notice about the graphs of odd functions? Odd functions are symmetric about the origin

  20. The 2 keys to sketching a graph of a polynomial are: f(x) = 6x4 + x3 – 12 Leading coefficient exponents Are they even or odd? (in front when in standard form!) Is it positive or negative?

  21. End Behavior Exploration • Work with a person sitting next to you. • Complete the WS together EXCEPT blanks at the VERY bottom

  22. End Behavior degree • If the __________ is even and the leading coefficient is _________, then • the left side of your graph goes _______ and the right side of your graph goes __________. positive up up degree • If the __________ is even and the leading coefficient is _________, then • the left side of your graph goes _______ and the right side of your graph goes __________. negative down down

  23. End Behavior degree • If the __________ is odd and the leading coefficient is _________, then • the left side of your graph goes _______ and the right side of your graph goes __________. positive down up degree • If the __________ is odd and the leading coefficient is _________, then • the left side of your graph goes _______ and the right side of your graph goes __________. negative up down
