Solutions to Assignment 2......Domains and difference quitients:

*****Please note, I have used the percent sign instead of infinity symbol

1a) [-3/2,%)

b) (-%,-7] , [-6,%)

c) (-%,%)

d) (-%,-4] , [4,%)

e) (-%,0) , (0,%)

f ( -%,-4/7) , (-4/7,%)

g) (-%,-6) , (-6,%)

h (-%,%)

2a) 8x+4h

b) (-4) / x²+xh)

Solutions to assignment 4: ('%' will stand for infinity, 'sqrt' means the square root)

1)(x² -5)/((x²-5)+sqrt(x-6))

2) (x/(x-2))/((x/(x-2) - 2)

3)Does not exist since -4 is not in the domain of g(x)

4a)[6,%)

b)(-%, -sqrt(11) ] , [ sqrt(11) , %)

c)(-%,2),(2,4),(4,%)
