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.

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 grap class=

Respuesta :

Answer: 1. B(4)   2. t = 6    3. t = _  (put any number from 8 to 12)

Step-by-step explanation:

The value of B(4) is greater than A(4), at t = 6 the values of the graph are the same, and the inequality B(t) < A(t) is true for t = 8 and t = 9.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a graph of a two function:

Functions A and B give the population of City A and City B, respectively, t years since 1990.

From the graph:

B(4) > A(4)

At t = 6, the function's values are equal.

A(6) = B(6)

There is only one value at which the function's values are equal.

From the graph:

B(t) < A(t)

The inequality true at

t = 8

t = 9

Thus, the value of B(4) is greater than A(4), at t = 6 the values of the graph are the same, and the inequality B(t) < A(t) is true for t = 8 and t = 9.
