The number of vhs movie rentals has declined since the year 2000 due to the popularity of dvds, as the following table shows. use a graphing calculator to determine the exponential regression equation that best fits the vhs rental data. let x represent the number of years since 2000.

Step-by-step explanation:

Given that x is no of years from 2000

So x takes values as 0,1,2....6

Take the corresponding values in y.

No.xy

1010.5

217.8

326.3

435.1

544.4

653.6

763.1

Mean of x =3

Mean of y = 5.372

r = correlation coeff =-0.9944

So best fit would be

Hence OPtion C is right answer.

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
