In a poll conducted prior to a certain election, 37% of respondents said they preferred candidate A, 33% said they preferred candidate B, and 30% said they preferred candidate C. At least how many people would have to be surveyed for you to be confident that candidate A is truly in the lead, candidate B is truly in second place, and candidate C is truly in third place?

  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.
