Write as a Function of x x^2+9y=4

$x^{2} + 9 y = 4$

Step 1

Subtract $x^{2}$ from both sides of the equation.

$9 y = 4 - x^{2}$

Step 2

Divide each term in $9 y = 4 - x^{2}$ by $9$ and simplify.

Divide each term in $9 y = 4 - x^{2}$ by $9$ .

$\frac{9 y}{9} = \frac{4}{9} + \frac{- x^{2}}{9}$

Simplify the left side.

Cancel the common factor of $9$ .

Cancel the common factor.

$\frac{9 y}{9} = \frac{4}{9} + \frac{- x^{2}}{9}$

Divide $y$ by $1$ .

$y = \frac{4}{9} + \frac{- x^{2}}{9}$

Simplify the right side.

Move the negative in front of the fraction.

$y = \frac{4}{9} - \frac{x^{2}}{9}$

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.

$f (x) = \frac{4}{9} - \frac{x^{2}}{9}$

Write as a Function of x x^2+9y=4
