idk i did't do it, but i am sure it is wrong

lets go slow

first step is \[f(2+h)=\frac{1}{(2+h)^2-3}\]
misty1212
  • misty1212
second step is to square the \(2+h\) i.e. do \((2+h)(2+h)=4+4h+h^2\) giving \[\frac{1}{4+4h+h^2-3}\]

third step is the arithmetic, final answer is \[\frac{1}{4h+h^2+1}\]
