Answer:
<h2>A. 2Pi</h2>Step-by-step explanation:
The given function is
Notice that the indepedent variable doesn't have any transformation, that means the period doesn't change. In other words, this function has the same period than its parent function which is .
Therefore, the answer is A.
The image attached shows the graph of this function, there you can observe the period of the function.
Also, notice that this function is verticall stretched by a scale of 2, which doesn't change its original period.
Answer:
Option D- y > x – 2 and y < x + 1
Step-by-step explanation:
To determine : Which system of linear inequalities is represented by the graph?
Solution : First we examine the graph
The shaded region in purple is drawn using two line
The first line above the origin passing through the points (0,1) and (-1,0)
The equation of line passing through two points is
So, the equation of that line
The second line below the origin passing through the points (0,-2) and (2,0)
The equation of line passing through two points is
So, the equation of that line
Now, to check the system of inequality substitute point (x,y)=(0,0)
First equation
means
Second equation
means
Therefore, Option D is correct.
The linear inequalities of the system is y > x-2 and y < x + 1
