R richie Apr 2010 9 0 May 14, 2010 #1 Hello I am having trouble with the following questions. for the function f(x) = 1/x where x is not equal to 0 a. find f(x+h) b. expand g(x) = (f(x+h) -f(x))/h in terms of x and h Any help would be appreciated. Thanks.

Thanks. Click to expand... (a) simply replace x with x+h (b) g(x)=(1/(x+h)-1/x)/h just do a direct substitution
