### Question Description

An exponential model should be used to model data if:

A scatter plot of ln y versus ln x fits a linear pattern.

A scatter plot of y versus ln x fits a linear pattern.

A scatter plot of y versus x fits a linear pattern.

A scatter plot of ln y versus x fits a linear pattern.

Which system of equations can be used to find the ​exponential​ function that passes through the points ) and ?

a. 2  = a(25/4)^b

4 = a(625/4)^b

b. 25/4 = ab^2

625/4 =  ab^4

c. 25/4 = a(2)^b

625/4 = a(4)^b

d. 2 = ab^(25/4)

4 = ab^(625/4)

Which system of equations can be used to find the ​power​ function that passes through the points (2, 10) and (8, 25)?

2 = a(10)^b

8 =a(25)^b

10 = a(2)^b

25 = a(8)^b

2 = ab^10

8 = ab^25

10 = ab^2

25 = ab^8
