Rolle's Theorem Question
if f(a)=f(b) then it is constant function, so every point c inthe interval (a,b) is zero.
I don't understand the terms constant function, is it supposedto be a horizontal line or it can be a parabola curve.
For example, when f(a)=f(b) and they both exist at the endpointthen it can be a parabola curve then it break the assumption thatf(a)=f(b) then it is constant function, so every point c in theinterval (a,b) is zero.
Please draw the picture to describe and explain
