Ground state energies and potential

[tyogav]

How to compare the ground state energies if diagrams containing x vs V are given. I saw a problem containing diagrams three potentials and they have asked to arrange them in order of their ground state energies. One was a potential well, and the other two had small perturbation in the middle. How to start this?

Post the graphs of the three potentials.
