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: 61725
Listen, I'm happy to help you cheat, but couldn't you have just ran this through a calculator? It's not that hard.
Answer:
$51
Step-by-step explanation:
Answer:
Ooh that is incorrect try again.
6 / 8 = 3/4
3/4 x 7 = 5 1/4
5 1/4 = $5.25
So, 7/8 of a pound of shrimp costs $5.25.
