The answer would be -12
A population of cheetahs has a birth rate of 5, so the growth is +5
The death rate is 15, then the population growth will be: 5 - 15= -10
Immigration means some cheetahs come from the outside, then the population growth become: -10 + 2= -8
Emigration means some cheetahs go to the outside of the area. The final population growth would be: -8 - 4= -12
