The set of ordered pairs represents a function. write a rule that represents the function.
(0,0), (1,7), (2,28), (3,63), (4,112)
y=

  y = 7x²

Step-by-step explanation:

One clue that the relation is quadratic is found in the second differences:

First differences are ...

Then second differences are ...

These are constant, indicating the function is 2nd-degree, or quadratic. The coefficient of the x² term is half the value of these second differences, so it will be 7.

When we compare y = 7x² with the given relation values, we find that no additional adjustment is needed in this rule.

A rule that represents the function is y = 7x².

Alternate solution

Another way you might approach this is to factor the y-values:

< 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
