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

inverse

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

x^{5} + 20 x^{4} + 160 x^{3} + 640 x^{2} + 1280 x + 1024

Solution steps

y = x^{\frac{1}{5}} - 4

Replace

x

with

y

x = y^{\frac{1}{5}} - 4

Solve for

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

x^{5} + 20 x^{4} + 160 x^{3} + 640 x^{2} + 1280 x + 1024

f (x) = x^{7} - 3

\frac{- 2 - 5 x}{4 x - 7}

f (x) = \frac{x ^{3}}{9}

ln (20 x + e)

\frac{\frac{\frac{10 - 3 y}{3}}{2}}{3}
