Need help with exponential functions
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 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
