Answer:
Range = {-1, 1, 3}
Step-by-step explanation:
<u><em>The question asks for the range.</em></u>
The function given is

The domain is the set of 3 numbers:
Domain = {4,6,8}
We need to find the range.
First, the range is the set of all y-values for which the function is defined.
When we will be given the domain with a set of numbers, the range would be the numbers that we get when we evaluate the the function at those numbers.
So, we evaluate the function (y-values) at x = 4,6, and 8.
At x = 4:

At x = 6:

At x = 8:

Thus, the range is:
Range = {-1, 1, 3}
Answer: Trapezoid!
Hope this helped alot!
B is true; pi= ~3.14. 3+4 is equal to 7, so because pi is greater than 3, pi+4>7
