What is the inverse of the function F(x)= 19/x^3?

AleksAgata [21]

set f(x) equal to y

y = 19/ x^3

swap x and y

x = 19/y^3

make y the subject

xy^3 = 19

y^3 = 19/x

$y = \sqrt[3]{ \frac{19}{x} }$

then just replace y with f^-1(x)

$f(x) = \sqrt[3]{ \frac{19}{x} }$

hope this helped! have a good day ~ •lipika•
