Over what interval(s) is the function increasing? a) -∞ < x < ∞ b) -∞ < x < 5 c) 5 < x < ∞ d) never

The function is never increasing, always approaching y=5 but never reaching it. Therefore D is the correct answer

< 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
