Question

What might be the possible difficulties in the modelling of the world’s population growth with an exponential function of the form

y = Ae^kx

Where A is the initial population when the modelling began, k (positive) is the continuous growth rate and x is the time (years).

Select all the correct answers.

Answer

There is no issue with this model as long term studies show that the world’s population grows exponentially.

Answer

The model is suitable for modelling the population growth in advanced economies with large populations but not suitable for modelling the population growth in less developed economies with small populations.

0%

Answer

The exponential function has no upper bound, that means the value of y is unlimited.

Answer

The model is unable to predict or accommodate unusually large change in population.
