     3/ Let f(z) =-F f(x) = . Find a function g(z) that is f stretched vertically by a r-1 factor of 5, then shifted left 8 and up 13. g(z) =  
  
  Solution
3. f(x) = 2/(x-1)
g(x) ----f stretched verticaly by a factor 5
5(2/(x-1) )
Shfited left by 8
5(2/(x-1 +8) ) = 5(2/(x+ 7) )
shifted up by 13
5(2/(x+ 7) ) = 10/( x+7) +13
g(x) = 10/( x+7) +13
4. h(x) = 2x^3 +4
y = 2x^3 +4
find inverse h^-1(x)
Plug x= y and y=x in h(x)
x= 2y^3 +4
2y^3 = ( x-4)
y^3 = ( x-4)/2
y = { ( x-4)/2}^1/3
h^-1(x) = { ( x-4)/2}^1/3
5. f(x) = 7/( x-5) and g(x) = 1/(x-2)
(f /g)(x) = divide both functions
( f/g) (x) = 7(x-2)/ ( x-5)
