Question

x ∈ -5,1,y ∈ 0,6
x ∈ (-∞,∞),y ∈ (-∞,∞)
x ∈ (-∞,∞),y ∈ 0,6
x ∈ 0,6,y ∈ -5,1

Explanation:

Step1: Observe x - values

The left - most x - value of the circle is approximately $x=-5$ and the right - most is approximately $x = 1$. So the domain of x is $x\in[-5,1]$.

Step2: Observe y - values

The lowest y - value of the circle is approximately $y = 0$ and the highest is approximately $y=6$. So the range of y is $y\in[0,6]$.

Answer:

$x\in[-5,1],y\in[0,6]$
