ANSWER

Warm Up # 4. ANSWER. Check HW 5.7. Since the term (x + 1) is to the second power(even power), it touches the x-axis without passing through. That is what a double root looks like on a graph. This is cubic – lazy s shape – positive leading coefficient – ends up going up. .

  1. Warm Up #4 ANSWER

  2. Check HW 5.7

  3. Since the term (x + 1) is to the second power(even power), it touches the x-axis without passing through. That is what a double root looks like on a graph. This is cubic – lazy s shape – positive leading coefficient – ends up going up.

  4. y= -3(x – 3)(x – 1)(x +2)2 Quartic – w or m ??? Up or down???

  5. Graph the intercepts, it is cubic – lazy s – positive leading coefficient – ends up going up. Make a quick sketch!

  6. A. B.

  7. Use the calculator – Stat Edit – x in L1 and y in L2 – STAT Calc Quad Reg

  8. 1 4 13 34 73 136

  9. Find the equation using finite differences. f(-3) =213, f(-2) = 25, f(-1) = -7, f(0) = -3, f(1) = -11, f(2) = -7, f(3) = 205

  10. Homework Practice workbook 5.8 # 1 – 27 odd 5.9 # 1, 5, 7, 10, 11
