  Morris \& Thorne \cite{morris1} proposed geometrical objects called
traversable wormholes that act as bridges in connecting two spacetimes or two
different points of the same spacetime. The geometrical properties of these
wormholes depend upon the choice of the shape function. In literature, these
are studied in modified gravities for different types of shape functions. In
this paper, the traversable wormholes having shape function
$b(r)=\frac{r_0\tanh(r)}{\tanh(r_0)}$ are explored in $f(R)$ gravity with
$f(R)=R+\alpha R^m-\beta R^{-n}$, where $\alpha$, $\beta$, $m$ and $n$ are real
constants. For different values of constants in function $f(R)$, the analysis
is done in various cases. In each case, the energy conditions, equation of
state parameter and anisotropic parameter are determined.
