If f(x) is a differentiable function and g(x)is a double differentiable function such that |f(x)|≤1|≤1 and f'(x)=g(x). If f2(0)+g2(0)=92(0)+2(0)=9. Prove that there exists some c∈(–3,3)∈(–3,3)such thatg(c).g''(c)<0.
Anyonee😭

I hated everything about discreet maths last semester and the questions are unbelievably hard for no reason, but the question you sent is all over the internet if you check it out!
Ohh I didn't search in internet 
Hopefully you found it
