Answer 2

the key here is that there must be one element of the range (y-values) for every element of the domain (x-values) but your x values repeat so this is not a function ;)

Answer 3

Complete the square and write the equation in standard form. Then give the center and radius of the circle.

Answer 4

x2 + y2 - 10x - 8y + 29 = 0
