Write as a Function of y y=f(-4)

$y = f (- 4)$

Step 1

Rewrite the equation as $f (- 4) = y$ .

$f (- 4) = y$

Step 2

Divide each term in $f (- 4) = y$ by $- 4$ and simplify.

Divide each term in $f (- 4) = y$ by $- 4$ .

$\frac{f \cdot - 4}{- 4} = \frac{y}{- 4}$

Simplify the left side.

Cancel the common factor of $- 4$ .

Cancel the common factor.

$\frac{f \cdot - 4}{- 4} = \frac{y}{- 4}$

Divide $f$ by $1$ .

$f = \frac{y}{- 4}$

Simplify the right side.

Move the negative in front of the fraction.

$f = - \frac{y}{4}$

Step 3

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

$f (y) = - \frac{y}{4}$

Write as a Function of y y=f(-4)
