The population of city is 7 million in 2015.

Step-by-step explanation:

It is given that the population of a city, P, in millions, is a function of t, the number of years since 2010.

It means, P = f (t).

We need to explain the meaning of the statement f (5) = 7 in terms of the population of this city.

f (5) = 7 means the population is 7 millions at t=5.

t = 5 means 5 years after 2010, i. e., 2010+5 = 2015

Therefore, the population of city is 7 million in 2015.
