求反函数 f(x)=-3/2 \sqrt[3]{x+4}-1

解答

求反函数

f (x) = - \frac{3}{2} 3 x + 4 - 1

\frac{- 8 x ^{3} - 8}{27} + \frac{- 8 x ^{2} - 8 x}{9} - 4

求解步骤

y = - \frac{3}{2} 3 x + 4 - 1

用

y

替代

x

x = - \frac{3}{2} 3 y + 4 - 1

求解

y, x = - \frac{3}{2} 3 y + 4 - 1

\frac{- 8 x ^{3} - 8}{27} + \frac{- 8 x ^{2} - 8 x}{9} - 4

in v erse \frac{4 x + 5}{3 x - 4}

in v erse f (x) = \frac{10}{x - 8}

in v erse f (x) = \frac{2}{n + 1}

in v erse arcsin (3)

in v erse \frac{5 x - 7}{- 8 x + 1}
