Let f: D → ℝ and let c be an accumulation point of D. Mark each statement True or False. Justify each answer.

(a) For any polynomial P and any c ∈ ℝ, limx→c P(x) = P(c).

---

(b) For any polynomials P and Q and any c ∈ ℝ,

---

(c) In evaluating limx→a– f(x) we only consider points x that are greater than a.

---

(d) If f is defined in a deleted neighborhood of c, then limx→c.f(x) = L iff limx→e + f(x) = limx→c- f(x) = L.
