Answer:
A
Step-by-step explanation:
Lets first solve the relation for "y". Shown below:
This is clearly an equation of a line in the form 
It will be a negatively sloped line, when graphed.
We can use vertical line test to determine function or relation. If a vertical line passes through only 1 point in the graph, we say that it is a function.
Think of a negatively sloped line. No matter where you draw a vertical line, it will only cut the line at 1 point.
So, this is definitely an equation of a function

Answer:
Step-by-step explanation:
Given:
The expression to simplify is given as:
In order to simplify this, we have to use the law of indices.
1. 
So, 
Substitute this value in the above expression. This gives,
Now, we use another law of indices.
2. 
So, 
Substitute these values in the above expression. This gives,
Finally, we further simplify it using the law 
So, 
Therefore, the given expression is simplified as:
