Morris and Thorne [M. S. Morris and K. S. Thorne, Am. J. Phys. 56, 395 (1988)] 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 the literature, these are studied in modified gravities for different types of shape functions. In this paper, the traversable wormholes having shape function b(r) = 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.
