請問這題要怎麼算

(Cx²+1, X²3 f(x) = {cx-1, x>² 73 find C so that f is continuous on (-∞0,00) 3. f(x) = 0

請問一下這題，謝謝٩(•̤̀ᵕ•̤́๑)

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.

想問b為什麼在3時不連續 ？ 我的想法是：在3時存在，而存在一定連續。
