Which kind of function best models the data in the table? Graph the data and write an equation to model the data. x y 0 –1 1 –2 2 –3 3 –4 4 –5 exponential; y = 3x – 1

quadratic; y = x2 – 1

linear; y = x – 1

linear; y = –x – 1

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
