Answer:
See diagram
Step-by-step explanation:
Start with parent function
The period of parent function is 
Consider function
You can rewrite it as
The period of this function is 
This gives you that the graph of the function
is twice compressed and translated 1 unit to the right graph of the parent function.
Answer:
x ≥ −42
Step-by-step explanation:
Let's solve your inequality step-by-step.
x/7≥−6
Step 1: Simplify both sides of the inequality.

Step 2: Multiply both sides by 7.
x ≥ −42
Mean = (6 + 12 + 13 + 13 + 16 + 18)/ 2 = 78/2 = 13
Mode = 13
Median = 0
Mean and mode are equal = 13
There is no median.
That would be y=6 I believe
