想請教這題的解法

3. Proof that there is only one intersect point between f(x) = 5x3 + 2x2 + 4x + 1 and g(x) = 2x2 + cos x. (Hint: use the mean value theorem) (10%) =

65.66怎麼證明，real solution是什麼？是真正的解法？

Finding a Solution In Exercises 65–68, use the Intermediate Value Theorem and Rolle's Theorem to prove that the equation has exactly one real solution. 65. x5 + x3 + x + 1 = 0 66. 2x5 + 7x – 1 = 0 -

圈起來的地方，為何講到連續性區間，括號就是中括號；可微分的區間就是用小括號啊？

:) THEOREM 3.3 Rolle's Theorem Let f be continuous on the closed interval [a, b] and differentiable on the open interval (a, b). If f(a) = f(b), then there is at least one number c in (a, b) such that f'(c) = 0.

求解釋~感謝🙏(◍•ᴗ•◍)
