Using the data in the table, describe the relationship between birth rate and infant mortality rate as the epidemiological transition occurs in a country.

Answer with Explanation:

The "Birth Rate" and the "Infant Mortality Rate" are directly proportional for the countries of Ethiopia, Nigeria and South Africa. This means that as the Birth Rate increases, the Infant Mortality Rate increases. The Infant Mortality Rates are also higher compared to the number of Birth Rates.

On the contrary, Egypt experiences a different relationship with its Birth Rate and Infant Mortality Rate. It has a higher Birth Rate than Infant Mortality Rate.

to answer your question:

f(x)= a^x.  if x=0, f(x)=1  if x=1, f(x)=a  if x=1, f(x)=a^a
