    So for this, we will be using exponential form, which is y = ab^x (a = initial value, b = growth/decay).

    Since we start off with 210 animals, that is our a variable.

    Next, since this is * decreasing * by 14%, you are to subtract 0.14 (14% in decimal form) from 1 to get 0.86. That will be your b variable.

    Putting everything together, your equation is y = 210 (0.86) ^x
