Answer:
.
For values of x>0, it can be rewritten as 
Step-by-step explanation:
For the expression:

We can apply this logarithmical property: 
Then,

If we assume values of <em>x </em>> 0 (non negative values for x), then the expression could be rewritten as follows:
, since 
We have to remember that <em>domain</em> (all possible values x) for logarithmic function is for all x > 0, or mathematically expressed as:
Domain: 
Answer:
The data should be from 1 to 2 with tick marks every 10th
Step-by-step explanation:
A)= 2/20 or 1/10
B)=16/20 or 4/5
C)=1/5
