m3 - smh and spings

I have a problem with understanding Hooke's Law and F = ma combined.

In the question in the attachment, the particle is to the left of the centre of oscillation and acceleration is always in the direction of x increasing and T is also in that direction?

for part a) Is the string taut at the stating position? If so why is it still -T? Is it anything to do with x now being -x?

If it's only taut at when the extension is +x the I would have had to assume shm to show shm.

I think I need some serious help in understanding.

Thanks
