Which kind of function best models the data in the table? graph the data and write an equation to model the data.

linear; y = x – 1

linear; y = –x – 1

quadratic; y = x2 – 1

exponential; y = 3x – 1

< 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
