Question

Help me pleaseeeee
An initial population of 400 deer decreases at an annual rate of 9%. Write an exponential function to model the deer population. What will the approximate population be after 3 years?
f(x) = (400 times 0.09)^x; 46,656
f(x) = 400 (0.91)^x; 301
f(x) = 400 (1.09)^x; 518
f(x) = 400 (9)^x; 301

Answer 1

400(1.09)^x

Answer 2

An exponential growth or decay function is a function that grows or shrinks at a
constant percent growth rate. The equation can be written in the form x f (x) = a(1+ r) or x f (x) = ab where b = 1+r
Where
a is the initial or starting value of the function
r is the percent growth or decay rate, written as a decimal
b is the growth factor or growth multiplier. Since powers of negative numbers behave
strangely, we limit b to positive values.

Omg thank youuuuuuuuu
