I have a lot of questions and I know I'm supposed to show all my work but the post would be insanely long, so I will show you what answers I have come up with on the ones that I managed to get that far. I know how to do these but I often get hung up on the fractions and trying to get rid of the exponents For functions: f(x)= (x+1)/(x-1) g(x)= 1/x Find: A. f+g I got 2x+2/x^2-x B. f-g I got 0 C. f*g I got x+1/x^2-x D. f/g I got x^2+1/x-1 E. f o g (x) I got 2x/1-x These ones I am having difficulty with, sorry for not showing my work, some answers would be very much appreciated though. Multiply: a. (x^2-2)^3 b. (x^2+3x+5)(x+2) c. (2x^2-6x)(2x-4) Divide and define restrictions: a. (2x^3-x^2+2x-3) / (x-1) b. (x^5-x^4-4x^3+8x^2-32x+48) / (x^2+4) c. (x^5-1) (x-1) Thanks again for the help, hopefully this is just the forum I was looking for!
