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?
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
