Answer:
The correct option is D.
Step-by-step explanation:
The given graph is the graph of a cosine function, which shifts 1 unit left.
The cosine function is defined as

Where, a is amplitude, b is frequency, c is phase shift and d is vertical shift.
If c>0, then the graph shifts c units left and if c<0, then the graph shifts c units right.
Since the graph show only phase shift and the graph shifts only one unit left, therefore required function is

Option D is correct.
Answer:
(-1)*(-1)=1
1*(-1)= -1
first option (-1) is the right answer.
Answer:
XZ = 44
KQ = 24
Step-by-step explanation:
XH is half of XZ, and XH is 22x so two times 22x will give you XZ.
XH times two equation - 2(22x)
XZ equation - 43x + 1
Set them equal
2(22x) = 43x + 1
44x = 43x + 1
x = 1
Put x in equation XZ
43(1) + 1 = 44
Step-by-step explanation:
Any lines that are parallel to each other have the same slope (coefficient of x is the same)
In this case, y = 2x + c.
Since it includes the point (0, 1), the y-intercept is 1 and that is c itself.
Hence, the equation of the parallel line is y = 2x + 1.
