Ok, So I got two problems I have no clue how to do or finish the first I got far on....
First
f(x) = 1/x+7
f(x+h) = 1/(x+h)+7
My work...
[ 1/(x+h)+7 ] - [ 1/x+7 ]
_____________________
h/1
Skip few steps.... Then
1(x+7) - (x+h)+7 / h [(x+h)+7](x+70
Dont know where to go from there.....
Second problem have no clue where to start or finish...
f(x) = Square Root of x+7
Help would be very appreciated!
