inverse of f(x)=5x^{1/3}+4

inverse

f (x) = 5 x^{\frac{1}{3}} + 4

\frac{x ^{3}}{125} - \frac{12 x ^{2}}{125} + \frac{48 x}{125} - \frac{64}{125}

Solution steps

y = 5 x^{\frac{1}{3}} + 4

Replace

x

with

y

x = 5 y^{\frac{1}{3}} + 4

Solve for

y, x = 5 y^{\frac{1}{3}} + 4

\frac{x ^{3}}{125} - \frac{12 x ^{2}}{125} + \frac{48 x}{125} - \frac{64}{125}
