Here's the first two

 

1.  Avg Rate of Change

 

f(9)  - f(5)            14 - (-2)             16

_______    =     _______   =        __       =      4

  9  -  5                 9 -   5                4

 

2.   (f/g)x   =  [ 4x^2 + 6x]  /  [ 2x^2 + 13x + 15 ]  =  [ 2x (2x + 3)] / [ (2x + 3) (x + 5)]  =

 

2x / (x + 5)

x^2 - 6x + 8 = x-2

x^2 - 7x -6 = 0

(x-7)(x+1) = 0

x = 7 or -1
