Answer:
Range is given by the second option: 
{
}.
Step-by-step explanation:
Range is the set of possible 
values in a given function.
Here, the function is defined by the following ordered pairs:
The y values of the function are {}
Therefore, the range is given as {}.
So, the second option is correct.
I may be wrong but I think it would be D, Since (even with the rounded edges) theres only 4 defined sides.
22h=22
So h=1
This answer is the only mistake in the equation
A) W + Y = 29
B) 11.95 W + 11.50 Y = 338.90
Multiply equation A by -11.5
A) -11.5 W + -11.50Y = -333.50 then add to B)
B) 11.95 W + 11.50 Y = 338.90
.45 W = 5.4
W = 12 and so
Y = 17
