In 2000, park rangers decided to introduce catfish in Lake Reelywhet. The population of catfish (in thousands) in Lake Reelywhet is related to the number of years since 2000 by the following function: w(a) = 1.125 - 0.675 * 1.1^-a.
What is the significance of the point (0, 0.45) to the function w defined above?
It does not lie on the graph of the function and therefore has no significance.
It is a vertical asymptote for the function.
It is the point where the graph intercepts the vertical axis.
It is the point where the graph intercepts the horizontal axis.
It is a horizontal asymptote for the function.
