Question #fa896
1 Answer
Using Bolzano's & Rolles Theorem w/ Monotony & proof of contradiction
Explanation:
also
so
-
f continuous in[0,1] -
f(0)=-1<0 -
f(1)=1>0
=> f(0)f(1)<0
-So, according to Bolzano's Theorem there is at least one
Supposed there is one more root
- All the criteria for Rolle's theorem are being met at
According to Rolle's theorem, there is one
Because
(ξ is greek letter used to mark the second root, nothing important. )
