inverse of f(x)=5x^{1/3}-1

inverse

f (x) = 5 x^{\frac{1}{3}} - 1

\frac{x ^{3}}{125} + \frac{3 x ^{2}}{125} + \frac{3 x}{125} + \frac{1}{125}

Solution steps

y = 5 x^{\frac{1}{3}} - 1

Replace

x

with

y

x = 5 y^{\frac{1}{3}} - 1

Solve for

y, x = 5 y^{\frac{1}{3}} - 1

\frac{x ^{3}}{125} + \frac{3 x ^{2}}{125} + \frac{3 x}{125} + \frac{1}{125}
