Determine the exponential regression for the data set. Which exponential equation BEST approximates the data set?

{(1, 4), (2, 12), (3, 32), (4, 60)}
A) y = 1.3(1.5)x
B) y = 1.3(2.5)x
C) y = 1.8(2.5)x
D) y = 2.3(3.5)x

Answer 1

C) y = 1.8(2.5)^x

Use the exponential regression function on a calculator to find a and b of the equation y = ab^x.

Answer 2

The answer is c) y= 1.8(2.5)^x
