The answer is A I am pretty sure. This is because in choice B, you would be dividing 7 and the sum of x + 5. In choice C you would not be multiplying 7 and the sum of x + 5. When he question asks for the product, it is asking for you to multiply. In choice D you would not just be squaring y, you would be squaring 2xy, which is not what we want. We only want to square y, therefore I believe the correct answer is A.

so,
$64=64*1/8 hour
•°•$64=8 hours
Statement 1 is false.
While it is true that some of the y-values have more than one corresponding x-value, this does not make the relation not a function. It would not be a function if some of the <em>x-values</em> had more than one corresponding y-values.
Statement 2 is true.
The domain of a function is all the x-values it encompasses. This function starts at 3 and ends at 8.
Statement 3 is false.
The range of a function is all the y-values it encompasses. This includes all the y-coordinates, but it does not express the range properly. The range is [6, 10].
Hope this helps!!
Answer:
7/10 or 0.7
