71. f(x)=x^2-1 c=2 x^2-1-3/ x-2 (x^2-4)/ (x-2) 2+2=4 is the slope worked by Rachel Rilling correct, checked by Marla Roper

73. Worked by BRYAN RUCKERRRRRRR =D correct checked by yo boi AARON HENDERSON!!

77. step 1 f(x)=[(x-6)^2/3-0]/(x-6) step 2 1/(x-6)^1/3 step 3 1/(0)^2/3= DNE Worked by Brooke Elias

81. Vx, except at x = -1 82. Vx, except at x = 3 and x = -3 Worked by Marla Roper 81 and 82 checked by Rachel Rilling 83. Worked by Jane Swanson

83 and 84 correct! checked by emily othold

85. all values X greater than one 86. all values of X other than X=0 Worked by Scott Trostle Checked By Brooke Elias

93) Worked and checked by Audrey Luecken

94. F’(1)- = (x-1)/(x-1) = 1 F’(1)+ = (x2-1)/(x-1) = (x-1)(x+1)/(x-1)

=x+1

=2

1 does not = 2

It is not differential at x = 1 because there is a sharp turn.
