inverse of f(x)=-2(x+2)^{1/3}-1

inverse

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

\frac{- x ^{3} - 3 x ^{2} - 3 x - 1}{8} - 2

Solution steps

y = - 2 (x + 2)^{\frac{1}{3}} - 1

Replace

x

with

y

x = - 2 (y + 2)^{\frac{1}{3}} - 1

Solve for

y, x = - 2 (y + 2)^{\frac{1}{3}} - 1

\frac{- x ^{3} - 3 x ^{2} - 3 x - 1}{8} - 2
