1. How would u go about finding the inverse of the following funcions:

(i can do the regular ones)

a. f:R\{1} ~ R, f(x)= x+1/x-1

b. f:R\{2/3}~R, f(x)= 2x+3/3x-2

2. Let f:S~R be given by f(x)=x-3/2x-1 where S=R\{1/2}

a. show that f°f is defined

b. Find f°f(x)

c. Write down the inverse of f

3. Also how would u go about solving ((x-4)/3)^2= x+2 for x?

Thanks, (ps ~ = arrow)
