Let & be continuous in [a,b] and differentiable in (a,b). It's true that:
a) f (a) = f(b) = 3 x € (a,b) such that the tangent line to the graph of at (nor f(no))
is horizontal.
b) there exists - (b)
c) f(a) > f (b) f is decreasing in (a,b)
d) fla)
<f(b) f([a,b]) =[f(a), f(b)]
e) f is strictly increasing in (a,b) ⇒ f'(x) >0, \₂ € (a, b)
