Answer:
B.
Step-by-step explanation:
We are given that,
The frequency of the function is
The maximum and minimum value is 12 and -6.
Also, the y-intercept is 3.
From the options, we have,
Options C and D have minimum value 6. So, they does not represent the given function.
We know, 'If a function has a period P, then the function will have the period
.
Also, 'The frequency is the reciprocal of the period'.
So, function will have the frequency
.
From the options, we see,
Option B have the frequency, i.e.
.
Option A have the frequency, i.e. 3
Thus, option A is not correct.
Hence, option B is the required sinusoidal function.
The population density of an area is the number of people living in per unit area. The most populated region is Region A.
<h3>What is Population Density?</h3>The population density of an area is the number of people living in per unit area. It is given by the formula,
The population density of the different regions is as follows,
Region A = 20,178 person /521 km² = 38.729 person/km²
Region B = 1,200 person /451 km² = 2.66 person/km²
Region C = 13,475person /395 km² = 34.114 person/km²
Region D = 6,980 person /426 km² = 16.385 person/km²
Hence, The most populated region is Region A.

Answer:
<em>f(x) = </em><em> x - 2 </em>
Step-by-step explanation:
Slope of the line: m =
y - = m( x -
)
f(x) = mx + b (b - is y-intercept)
(0, - 2) Coordinates of y-intercept
(4, - 3)
m = =
<em>f(x) = </em><em> x - 2</em>
