Question

Use the exponential regression equation that best fits the data (2,7), (3,10), (5,50), and (8,415)

to estimate the value of y when x = 7.

A.

47.32
B.

61.56
C.

99.87
D.

200.64

Answer 1

Use your normal linear regression on the function log(f(x))
So find the line of best fit for the points
(2,1.9459), (3,2.3026), (5,3.9120), and (8,6.0283)
Then, when you have the line y = mx+b, your exponential best-fit function will be e^y
