Question

Functions A and B give the population of City A and

City B, respectively, t, years since 1990. In each
function, the population is measured in millions.
Here are the graphs of the two functions.
For what value of t is the equation A(t)= B(t) true?

Answer 1

`t = 6`

Explanation:

Given

See attachment for graph

Required

At what point is A(t) = B(t) true

This point which makes A(t) = B(t) is the point which they intersect.

From the graph, A(t) and B(t) intersects at
`t = 6`

Hence, the value of t is 6
