Provide an appropriate response.The total number N of rabbits on a farmer's property, assuming unlimited resources and space, can be approximated by the function N(x) = 50e0.452x, where x = 0 corresponds to the initial number of rabbits, and x = 1 corresponds to the number of rabbits after one year, and so on. The function is graphed on a graphing calculator-generated screen. Interpret the meanings of x and y in the display at the bottom of the screen.
