Why not?: The following statements are all false. Explain why. (Use words, counterexamples and/or graphs wherever you think appropriate). This exercise is graded differently. Each part is worth 3 points. (a) If f(r) is defined on (a, b) and f(c)-0 and for some point c € (a, b), then f'(c)-0. (b) If f(a)- 2x+1 if ≤0 ²+2r if x>0 then f'(0)-2. (e) The tangent line to f at the point where za intersects f at exactly one point. (d) If f'(r) > g'(r) for all z € (a,b), then f(x) > g(r) for all z € (a,b). (e) If f is a function and fof is differentiable everywhere, then f is differentiable everywhere. (Recall fof is the notation indicating f composed with itself)
