Question

A population of 240 birds increases at a rate of 16% annually. Jemel writes an exponential function of the form f(x) = abx to represent the number of birds after x years. Which values should she use for a and b?

Answer 1

For this case we have a function of the form:
f (x) = a (b) ^ x
Where,
a: initial population
b: growth rate
x: time
Substituting values we have:
f (x) = 240 (1.16) ^ x
Answer:
she should use for a and b:
a = 240
b = 1.16
