For this case we have a function of the form:
 [tex] y = A * (b) ^ x [/tex]
 Where,
 A: initial population
 b: growth rate
 x: number of years.
 We then have the following function:
 [tex] y = 210000 * (1,125) ^ x [/tex]
 For x = 4 years we have:
 [tex] y = 210000 * (1,125) ^ 4 y = 336379[/tex]
 Answer:
 the formula for exponential growth is:
 y = 210000 * (1,125) ^ x
 The population of Canyon Edge after 4 years is:
 y = 336379
