The function is $\"x+(y-1)^2=0\"$ .

Find the bottom half of the parabola.

Solve the equation for $\"y\"$ .

$\"x+(y-1)^2=0\"$

$\"(y-1)^2=-x\"$

$\"y-1=\\pm$

The negative sign of the function is the bottom half of the parabola.

Hence, $\"y-1=-$

$\"y=1-$ .

Bottom half of the parabola is $\"f(x)=1-$ .
