The true statement is that; In 1990, there were 5.33 billion people.

What is an exponential function?

The term exponential function refers to a function which increases or decreases exponentially.

Let us consider the function, P(t)=641+11e−.08t;  we can see that the true statement is that; In 1990, there were 5.33 billion people. This is because, the negative sign shows that the population of the earth is decreasing and there were more people in 1990 than there is today.
