Answer:

<h2>√30/5 is the right answer.</h2>
Answer:
A is the only possible correct answer since the center of that shape is x =-1
X = -126/5 or -25.2 or -25 1/5
Answer:
D: {-20, -13, 1, 6}
R: {-20, -8, 11, 13}
Step-by-step explanation:
Given the relation, {(–20, 11), (6, –8), (1, –20), (–13, 13)}, all x-values (inputs) make up the domain of the relation while all y-values make up the range of the relation.
Therefore:
Domain: {-20, -13, 1, 6}
Range: {-20, -8, 11, 13}
