渐近线 f(x)=(x+3)/(x(x+9))

解答

渐近线

f (x) = \frac{x + 3}{x ( x + 9 )}

垂直 : x = - 9, x = 0, 水平 : y = 0

求解步骤

\frac{x + 3}{x ( x + 9 )}

的垂直渐近线:

x = - 9, x = 0

\frac{x + 3}{x ( x + 9 )}

的水平渐近线:

y = 0

\frac{x + 3}{x ( x + 9 )} :

无

垂直 : x = - 9, x = 0, 水平 : y = 0

in v erse y = x + 4

d o main \frac{- e ^{- x}}{1 + e ^{- x}}

d o main f (x) = \frac{3 + 4 x}{x - 1}

in f l ec t i o n f (x) = x^{4} - 4 x^{3} + 3
