Then find all relative maximum and minimum points of the function. 1. f(x) = x3 + 6x2 ( 9x + 2 Rational roots:______________ Irrational roots:______________ Non-real roots:______________ Relative maximum points:____________ Relative minimum points:_____________ 2. f(x) = x4 + x2 ( 20 Rational roots:______________ Irrational roots:______________ Non-real roots:______________ Relative maximum points:____________ Relative minimum points:_____________ 3. f(x) = 12x3 + 44x2 ( 23x ( 105 Rational roots:______________ Irrational roots:______________ Non-real roots:______________ Relative maximum points:____________ Relative minimum points:_____________ 4. f(x) = x6 ( 6x5 ( 45x4 + 284x3 + 279x2 ( 3510x + 4725  Rational roots:______________ Irrational roots:______________ Non-real roots:______________ Relative maximum points:____________ Relative minimum points:_____________ 5. f(x) = x4 + 9x3 + 26x2 + 28x + 8 Rational roots:______________ Irrational roots:______________ Non-real roots:______________ Relative maximum points:____________ Relative minimum points:_____________ 6. f(x) = 7x4 ( 26x3 ( 22x2 ( 109x ( 30 Rational roots:______________ Irrational roots:______________ Non-real roots:______________ Relative maximum points:____________ Relative minimum points:_____________ 7. Sales for a new CD can be modeled by the function: f(x) = (.000795x4 + .0256x3 (.2834x2 + 1.161x + .2971, where x is the number of months since the release of the CD and f(x) is the number of CDs sold in thousands. About how long did the CD stay on the shelves? What was the most number of CDs sold in any one month?    2 3 X Y " # H I K L W Y Z [ ` a b c d i j n o p   ) * + ʼhj j-hGS hahahGS hGSH*hahaCJaJ j-ha haH*jhaUmHnHuh;'haH:[\   2 3 X Y  " # gda# I J K o p  X Z z {  0 gda+ , - 0 2 3 7 8 > ? @ G H I J O S W X Y Z z {         !
