Which point is the best approximation of the relative maximum of the polynomial function graphed below?

GarryVolchara [31]

Answer:

The best approximation is the point $(-1.4, 16.9)$

Step-by-step explanation:

we know that

Observing the figure

The x-coordinate of the relative maximum belong to the interval ----> $(-2, -1)$

The y-coordinate of the relative maximum belong to the interval ----> $(15, 20)$

see the attached figure to better understand the problem

therefore

The best approximation is the point $(-1.4, 16.9)$

weqwewe [10]

Answer:

1,887,436,800

Step-by-step explanation:

f(t) = a·b^t

f (t) = number of cases at year t

a = starting value = 1800 in 1983

b = growth factor = 2

t = years since 1983 = 2003 - 1983 = 20

f(t) = 1800·(2)^20 =
