Question

The graph shows a function that models the value V (in millions of dollars) of

stock portfolio as a function of time t (in months) over an 18-month period.
Identify any extreme value of the function

Answer 1

Option (B)

Explanation:

A function that models the value V of the stock portfolio as function of t is given by the graph.

Each grid on the y - axis measures =
`(3-2)/(4)` = 0.25

Each grid on the x - axis measures = 1 unit

Local maximum from the graph = (3, 2.5)

Global minimum = (13, 0.75)

Global maximum = (18, 3)

Local minimum = (13, 0.75)

Here local and global minimum of the function will be same as (13, 0.75).

Therefore, Option (A) will be the answer.
