Consider the following relation.

1−x‾‾‾‾‾√−4y=11−x−4y=1

Step 1 of 3 :  

Rewrite the relation as a function of x.

We are given the following relation:

\[
\sqrt{1 - x} - 4y = 1
\]

### Step 1: Isolate \( y \)
First, let's isolate \( y \) by solving for \( y \) in terms of \( x \).

1. Start by moving the square root term to the other side of the equation:
   \[
   -4y = 1 - \sqrt{1 - x}
   \]
2. Now, divide both sides by \(-4\) to solve for \( y \):
   \[
   y = \frac{1 - \sqrt{1 - x}}{-4}
   \]
   Simplifying the equation:
   \[
   y = \frac{\sqrt{1 - x} - 1}{4}
   \]

Thus, the relation rewritten as a function of \( x \) is:
\[
y = \frac{\sqrt{1 - x} - 1}{4}
\]
