The answer is -12

Starting with a base of 0 cheetahs:

  1. 5 are born (0+5=5)
  2. 15 die (5-15=-10)
  3. 2 come (-10+2=-8)
  4. 4 leave (-8-4=-12)

After everything happens, the cheetah population has overall lost 12 cheetahs.

The population growth(r) would be -12.

Population growth=(Births-Deaths) + (Immigration-Emigration)

5-15 + 2-4=-12
