Oscillations: The spring with varying force constant

Please see attachment. Thanks.

---
Many real springs are more easily stretched than compressed. We can represent this by using different spring constants for and for . As an example, consider a spring that exerts the following restoring force:

A mass on a frictionless, horizontal surface is attached to this spring, displaced to by stretching the spring and released.

1) Find the period of the motion.
Express your answer in terms of and .

2) Does the period depend on ?

yes

no

3) Are the oscillations simple harmonic?

yes

no

4) What is the most negative value of that the mass reaches?

5) Is the oscillation symmetric about the point ?
