What is the domain of the relation graphed below? On a coordinate plane, an ellipse intercepts the x-axis at (negative 4, 0) and (4, 0) and intercepts the y-axis at (0, 1) and (0, negative 1).
domain: StartSet x vertical line x belongs to all natural numbers EndSet
domain: StartSet x vertical line x belongs to all real numbers EndSet
domain: StartSet x vertical line negative 4 less-than-or-equal-to x less-than-or-equal-to 4 EndSet
domain: StartSet x vertical line negative 1 less-than-or-equal-to x less-than-or-equal-to 1 EndSet

Domain: {x|-4<=x<=4}

Step-by-step explanation:

Domain refers to the set of the 1st elements, so the x values. In the image we see the ellipse go through both x and y axis but since the question is asking for domain and NOT range (range meaning y values) we can conclude that we need the x values, those being -4 and 4.

I took the review and got it right

On Edge 2020 it's answer C

Domain: {x|-4<=x<=4}

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
