What's the missing number?

Need ! discuss how to convert the standard form of the equation of a circle to the general form. 50 points

What is the domain of the given function? {(3,-2), (6, 1), (-1, 4), (5,9), (-4, 0); o {x | x= -4,-1, 3, 5, 6} o {yl y = -2,0, 1,4,9} o {x|x = -4,-2, -1,0, 1, 3, 4, 5, 6, 9} o y y = 4,-2, -1, 0, 1, 3, 4, 5, 6, 9}

Select the conic section that represents the equation. 3x2 + 3y2 -2x + 4 = 0
