解答

临界点

∣ sin (4 x) + 5 cos (4 x) ∣

无

求解步骤

∣ sin (4 x) + 5 cos (4 x) ∣

找到

f^{'} (x)

等于零或无定义的点

无

r an g e \frac{1}{e ^{x} + 1}

in f l ec t i o n f (x) = 18 x^{4} - 108 x^{2}

in v erse f (x) = 2 + 3 2 - 3 x

d o main y = \frac{4 x ^{2} - 5}{2 x ^{3} + x}

a sy m pt o t es f (x) = \frac{- x ^{2} + 25}{4 x + 20}
