Let f (x) = square root sign over x and g (x) = (x+2) (x-3).

a) Find f and g and find domain of f and g.

b) Find f/g and find domain of f/g.

If you can explain this to me in elementary word, I would greatly appreciate your time. I'm stumpted on functions.

a) The functions f and g are given. What do you mean by "finding" them? As for their domains, just look for any x-values which wouldn't work in each function. Their domains are everything else.

b) The function f/g is just f divided by g. So divide f by g, and simplify, if possible. The directions for the domain are the same as for part (a).
