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

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

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

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

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
