Functions A and B give the population of City A and City B, respectively, t years since 1990. In each function, population is measured in millions. Here are the graphs of the two functions

Which function value is greater: A(4) or B(4)?

Are there one or more values of t which the equation A(t) = B(t) is true? If so, which one or which ones?

Identify at least two values of t at which the inequality B(t) < A(t) is true.
