The population of Afghanistan is growing at a rate of 1.3% per year. In 2014 there were 30 million people in Afghanistan. The population (in millions) of Afghanistan x years after 2014 can be approximated by the function f(x)=30(1.013)^x

a. Use the function to predict the population in Afghanistan in 2024.
b. Use the function to predict the population in Afghanistan in 2100.
c. Use the function to predict when (during what year) the population of Afghanistan will reach 50 million. (Feel free to use the online equation solver and/or grapher for this one.)
