The table shows the number of internet users worldwide since 1994.
(A) Let x represent the number of years since 1994 and find an exponential
regression model (y = ab*) for this data set.
(B) Use the model to estimate the number of hosts in 2025 (to the nearest
million).
(A) Write the regression equation y = ab*.
y =
