Question

X2 + (y - 1) 2 = 4 .............................

Answer 1

`x=\pm √(6-2y)`

`$y=(1)/(2) (6-x^2)$`

Explanation:

`x^2+(y-1)\cdot 2 =4`

`x^2+2y-2 =4`

`x^2+2y =6`

I will solve it for
`x`

`x^2 =6-2y`

`x=\pm √(6-2y)`

Solving for
`y`

`$y=3-(x^2)/(2) $`

`$y=(1)/(2) (6-x^2)$`

Answer 2

Explanation:

x²+(y-1)²=4

x²+y²+1-2y=4

x²+y²-2y=3
