if `f(x)` is a differentiable function wherever it is continuous and `f^(')(c_(1))=f^(')(c_(2))=0,f^(``)(c_(2))lt0`,
`f(c_(1))=5,f(c_(2))=0` and `(c_(1)gtc_(2))`
Now answer the following questions (1 to 2)
Q. if `f(x)` is continuous is `[c_(1),c_(2)]` & `f^(``)(c_(1)-f^(``)(c_(2))lt0`, then minimum number of roots of `f^(')(x)=0` in `[c_(1)-1,c_(2)+1]` is
