I'm not understanding how the MVT can be used to prove that there is a zero. How would you do this question?

With the first question, I have zero clue what to do...

And for the second question, I managed to do part a and part b but kind of lost with part c.

For all t>0 (and semi-equality at t=0)



Which is simple enough to prove case-wise

Integrate both sides from 0 to x>0 to obtain:



Then add one throughout the inequality to obtain what was to be shown.

Do I need to find some sort of interval to use MVT or IVT?
