Answer:
(0,0), (0,1), (1,2), (1,3)
Step-by-step explanation:
To determine what makes ordered pairs a function, we have to make sure each input (x) goes to exactly one output (y).
The reason this is the answer is that each input doesn't have exactly one output. (0 goes to 0 and 1. 1 goes to 2 and 3).
 
        
             
        
        
        
Answer:
x=5
y=6
Step-by-step explanation:
If you add the two, it turns into 2y=12. That means y=6. So then x would equal 5 if you bring y into one of them.
 
        
             
        
        
        
Answer:

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:

1) Period
Since the period of a basic secant and basic sine function 

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"

 
        
                    
             
        
        
        
2x+12=18. 2x+12=-18
Subtract 12 from both sides 
2x=6. 2x=-30
Divide both sides by 2
X=3. X=-15
