Hey could someone help me with this question please?
Simplify each expression. That is, write as a single fraction, fully factored, with no common factors and only positive exponents.
a)
[f(2+h) - f(2)]/h where f(x) 2/x

anonymous · Answer

first step is 
$$f(2)=\frac{2}{2}=1$$

anonymous · Answer

then 
$$f(2+h)-f(2)=\frac{2}{2+h}-1$$
$$=\frac{2-(2+h)}{2+h}=\frac{-h}{2+h}$$

ohhh ok
thank you so much.

anonymous · Answer

not done yet

anonymous · Answer

you have to divide this by h

anonymous · Answer

the h cancels and you are left with 
$$\frac{-1}{2+h}$$

anonymous · Answer

oh that makes sense now
thanks a lot, i just joined this site and it helps soo much. Have a good day, and thanks again
