Answer:
A
Step-by-step explanation:
Consider the parent function
The graph of this function is represented as red graph in attached diagram.
Now consider the function 
Remind main translations of the graph of the function
- translation a units to the right;
- translation a units to the left;
- translation a units up;
- translation a units down.
In your case, the graph of the function
is translated graph of the function
2 units to the left (blue graph). So, correct answer is option A.
Answer:
The value of Cos (-Ф)
.
Step-by-step explanation:
Given Trigonometric function as :
sin( - Ф ) = 
- sin Ф = 
So, sin Ф = 
Now, as sin Ф = 
So ,
= 
So, perpendicular = 3
And hypotenuse = 5
Now,<u> From Pythagoras Theorem</u>
Base ² = Hypotenuse² - Perpendicular²
Or, Base ² = 5² - 3²
Or, Base ² = 25 - 9
Or, Base ² = 16
∴ Base = 
I.e Base = 4
Now, Cos Ф = 
So, Cos Ф = 
Now , Since
Cos ( - Ф ) = Cos Ф
So, Cos ( - Ф ) = Cos Ф = 
Hence The value of Cos (-Ф)

The Answer is 2
34.989.I used a physics book
Put x=-2 in x-y=-2
-2-y=-2
-y=0
y=0
x=-2
that's your answer.
