Which quadratic regression equation best fits the data set?

A.

Step-by-step explanation:

We are given the table,

x                             y

1                            20.4

2                           60.5

3                           86.8

4                           122.4

5                           180.4

6                           241.2

7                           420.8

Using the regression calculator, we get that,

So, option A is correct.

answer:

what is your question that you ask

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
