求反函数 f(x)=((-12-2n))/3

解答

求反函数

f (x) = \frac{( - 12 - 2 n )}{3}

- \frac{3 n + 12}{2}

求解步骤

y = \frac{- 12 - 2 n}{3}

用

y

替代

n

n = \frac{- 12 - 2 y}{3}

求解

y, n = \frac{- 12 - 2 y}{3}

- \frac{3 n + 12}{2}

a sy m pt o t es f (x) = \frac{ln ( x )}{x}

y = - x

d o main y = \frac{2 x - 1}{x ^{2} - x}

e x t re m e f (x) = 0.8 x + \frac{72}{x}

d o main f (x) = \frac{x ^{2} - x - 12}{x ^{2} + x - 6}
