I need a very fast answer to this question please I’m in a hurry

Answer 1

$f(x)=\frac{1}{x+2}$

To find f(3 + h) we need to substitute x = 3 + h, into the function, as follows:

$\begin{gathered} f(x)=\frac{1}{(3+h)+2} \\ \text{ Combining similar terms:} \\ f(x)=\frac{1}{h+(3+2)} \\ f(x)=\frac{1}{h+5} \end{gathered}$
