$x^{3} + y^{7} = 9$

Step 1

Subtract $x^{3}$ from both sides of the equation.

$y^{7} = 9 - x^{3}$

Step 2

Take the specified root of both sides of the equation to eliminate the exponent on the left side.

$y = \sqrt[7]{9 - x^{3}}$

Step 3

To rewrite as a function of $x$ , write the equation so that $y$ is by itself on one side of the equal sign and an expression involving only $x$ is on the other side.

$f (x) = \sqrt[7]{9 - x^{3}}$
