Which of the following relations DOES NOT represent y as a function of x. (hint: you may choose more than one answer) {(-6,3), (2,0), (3,-4), (1,8)}
{(-6,3), (2,0), (3,-4), (1,8)}

{(2,2), (1,5), (5,4), (2,4)}
{(2,2), (1,5), (5,4), (2,4)}

{(-6,2), (0,1), (-4,8), (3,8)}
{(-6,2), (0,1), (-4,8), (3,8)}

{(4,8), (4,2), (2,6), (1,6)}
{(4,8), (4,2), (2,6), (1,6)}

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

tangent

step-by-step explanation:

the answer is y = 11.54

hope this : )
