True or False?(10%)Justify your answers.A function f is defined on the interval[a,b] (a)If f(a)>0 and f(b)<0 then there must exist at least one number c in (a,b),for which f(c)=0 (b)If f is continuous on [a,b]with f(c)=0 for some number c in (a,b), then f(a) and f(b) have opposite signs. 3. Let f be a differentiable function. Use the chain rule to show that:if f is odd,then f' is even.(10%) 4.
