Question

research then analyze the belief in Manifest Destiny and explain how the concept influenced the development of the frontier

Answer 1

Manifest Destiny was a major influence on how the frontier developed. Manifest Destiny is the doctrine that our land was one that was destined to stretch from sea to shining sea. The reason that this was influential in the frontier's development is that when plans were being made, instead of slowly expanding outwards, the country exploded out living a middle frontier that was neither as developed as California or the East. 

Answer 2

Manifest destiny has to do with the expansion of the west.
