lawyer [7]2 years ago
6 0

Answer:

y = 2x + 3

Step-by-step explanation:

the slope is 2 so the line parallel will have a slope of 2

y-9 = 2(x-3)

y-9= 2x - 6

y = 2x +3

What are the period and vertical shift of the cosecant function below?
lutik1710 [3]

Answer:

y=acsc(bx-c)+d\\y=csc(\frac{1}{2}x)+2\\P=\frac{2\pi}{b}\Rightarrow P=\frac{2\pi}{\frac{1}{2}} \Rightarrow P = 2\pi*2 \Rightarrow P=4\pi\\d=2

Step-by-step explanation:

The trigonometric functions have some features like amplitude, period, phase shift, and vertical shift.

Retrieving the original cosecant graph and copying and attaching it below we have this function:

y=cosec(\frac{1}{2})x+2

1) Period

Since the period of a basic secant and basic sine function 2\pi

y=acsc(bx-c)+d\\y=csc(\frac{1}{2}x)+2\\P=\frac{2\pi}{b}\Rightarrow P=\frac{2\pi}{\frac{1}{2}} \Rightarrow P = 2\pi*2 \Rightarrow P=4\pi

2) Vertical Shift

This value affects the graph by displacing it from x-axis.

The Vertical Shift does not need calculation for it is given by the parameter "d"

y=acsc(bx-c)+d\\y=csc(\frac{1}{2}x)+2\\ d=2 \: (Vertical\:Shift)
