Yes it is a function. It passes the vertical line test. In other words, it is impossible to draw a single vertical line through more than one point on the V shaped graph. Any input leads to exactly one output.
The domain is the set of all real numbers. This is because we can plug in any x value leading to some specific y value. There are no holes or gaps or jumps to indicate we must restrict any given x value. The domain would not be the set of whole numbers only because values between the whole numbers (eg: decimal values like x = 2.75) work just fine.
The range is the set of y values such that y is either 0 or larger than 0. In short,
the range is 
. Notice how any point on the V shaped graph has a y coordinate that is either 0 or larger than 0. It is impossible to get a y value that is negative.

In summary,
Yes it is a function
Domain: all real numbers
Range:

So
the answer is choice B
Answer:
28 feet farther than 1st ball.
Step-by-step explanation:
We have been given that Susan threw a softball 42 yards on her first try and
yard on her second try.
To find second ball is how much farther from the 1st ball, we will subtract 42 yards from
yards.
Let us have a common denominator.


Therefore, Susan thrown the second ball 28 feet farther from the 1st ball.
