3. The range of a cosecant function is . The equations of two consecutive asymptotes of the function are x = 0 and x = 2pi . The function is not a reflection over the x-axis. What is the equation of this cosecant function?

Respuesta :

Answer:

-2

Step-by-step explanation:

The  midline  of  this  function  is  y  =  [ -9  + 5 ]  / 2   =  -4/2 =  -2

 

The amplitude of the  function  is abs value ( [-9  -5] /2)  =  abs value (-14/2 )  =abs value (-7)   = 7

 

The period  is  twice as  long as  the regular csc function

 

The equation is

 

y  = 7 csc (x/2)  - 2

The equation of a cosecant function can be obtained by finding the variables in the general form of the function

[tex]The \ cosecant \ function \ equation \ is \ f(x) = \mathbf{7 \cdot csc\left(\dfrac{1}{2} \cdot x\right) - 2}[/tex]

The reason the above function is correct is as follows:

Question part missing: The part of the question that appear missing as obtained from a similar question is as follows;

The cosecant function range = (-∞, -9)U{5, ∞)

The given parameters are;

The consecutive asymptotes of the function are at x = 0, and x = 2·π

The function is not a reflection over the x-axis

The general form of the cosecant function is f(x) = A·csc(B·x + C) + D

Where:

A = The amplitude = (Maximum - Minimum)/2

The parent cosecant function range = (-∞, -1]U[1, ∞), a difference between maximum and minimum of 2, and having an amplitude of 2/2 = 1

The difference between the given maximum and minimum is 5 - (-9) = 14

∴ The amplitude, A = (5 - (-9))/2 = 14/2 = 7

A = 7

B: The period factor

The consecutive asymptote in the parent function, represent half a period

Therefore;

The period, T = 2·π/B = 2 × 2·π = 4·π

B = 2·π/4·π = 1/2

B = 1/2

C: Horizontal shift

Given that x = 0 is an asymptote, we have;

csc(B×0 + C) = ∞

csc(C) = ∞

1/csc(C) = 1/∞ = 0

sin(C) = 0

C = 0

D: Vertical shift

The vertical shift, D = (Maximum + Minimum)/2

D = (-9 + 5)/2 = -2

D = -2

Therefore, the equation of the cosecant function is given by plugging in the values of A, B, C, and D as follows;

f(x) = 7·csc((1/2)·x + 0) + (-2)

[tex]f(x) = \mathbf{7 \cdot csc\left(\dfrac{1}{2} \cdot x\right) - 2}[/tex]
