We already know the solutions for quadratic potential.
In this particular problems only those states will be allowed which have their wave function continuous at the boundary.
Since wave function is essentially zero in left half so only those wave functions are allowed which vanish as they approach to Y-axis(fig (b)).
I will attach the solution.
Let me know if that helps or if you have further queries(related
to the same question).
regards,
note: this question should be asked in advanced physics.
