Ihave already done most of the calculations, just looking for someone to me interpret them . i already know the answer to question (i), just wanted to give you a better idea of the whole problem.
assume the boolean matrix below is mr and that mr represents the relation r where r represents the connecting flights that an airline has between 4 cities: a, b, c, and d. so there is a 1 in row x column y iff there is a connecting flight between (from) city x and (to) city y. that is, the rows of the matrix represent the cities of the origins of the flight and the columns represent the destination cities. let the 0 in row d and column d stand for planes cannot

< 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

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
