(Answers provided by Aimee, Lauren, and Emily) || Student Feedback || Teacher Feedback || the question must read f(-2) = 0 || A: false. the factor should be x-2 E: False because of the Factor Theorem (pg 216) the factor x + 2 needs to be x - 2. || COOL COLORS!!

 * 63.  L: False. The rule is f(k) = k - x, so

Correct || get a remainder of 3. || A: false, the remainder is 2 E: True. I foiled the problem and then divided by x -1. I was left with a remainder of 3 || ANswer is TRUE || Connections for Polynomial Functions." || A: A E: A x + 3 is a factor of f(x) because of the Fundamental Connection for Polynomial Functions (pg 217) and the Factor Theorem (pg 216). || Correct || example of it being used. When following that rule, 2/3 is not an option. || A: E. when i graphed the function all the other possible roots were x-intercepts. E: E because 2/3 is irrational.
 * 64. L: True. I foiled and used long division to
 * 65. L: A. See the green box on page 217, "Fundamental
 * 66. L: E. On pg. 219 is the Rational Zeros Theorem & an

<span style="color: rgb(4,0,184);">L: By the way, guys, 1 isn't an x-intercept (Aimee?!), and 2/3 isn't irrational. || Correct || x - 2, and the remainder was 17, not 3. || <span style="color: rgb(123,10,209);">A: B, the remainder when the equation is divided by x+2 is 1, not -3 <span style="color: rgb(236,24,24);">E: B. The remainder when the equation is divided by <span style="color: rgb(236,24,24);">x - 2 is 17 not -3. || Correct || problem, you can use the Rational Zeros Theorem to find possible roots and then plug them all in using synthetic division, and you'll find that none of them work. || <span style="color: rgb(134,19,221);">A: A, i foiled the equation to get x cubed - x squared +x+5 and divided by x squared +1 and got a remainder of x+6. So it's not true. <span style="color: rgb(236,24,24);">E: A because you cannot divide the equation by x <span style="color: rgb(236,24,24);">squared + 1. <span style="color: rgb(4,0,184);"> L: Aimee, when you foil the equation, you should get - 2 x squared, not - x squared. Emily, you //can// divide the equation by x squared + 1... :-P || E is the correct answer (see graph) ||
