I assume that your formula is   h(x) = + .


To avoid ambiguity,  you should write it as   h(x) = (1/sqrt(2x+1)) + sqrt(2x+1)

using PARENTHESES to show the fraction correctly  (if the formula is as I assumed).


    f(x) = 2x+1;


    g(x) =  + .



First the function  f(x)  converts  "x"  into  "2x+1";


Then the function  g(x)  converts  "2x+1"  into   + .
