The relation which is a function is; Choice A;<em> {(6, −4), (5, 8), (−3, 6), (−4, −4)}</em>
<h3>What is a function?</h3>
In mathematics, a function from a set of values for variable x to a set of values for variable y assigns to each element of x only one element of y. The set X is called the domain of the function and the set Y is called the codomain of the function.
On this note, since in Choice A, each x-value is mapped distinctively to one value of y, Choice A is a function.

Answer:
-7
Step-by-step explanation:
Equation: 2x - 4 = -18
First, add 4 to both sides:
2x = -14
Finally, divide both sides by 2:
x = -7
Check (optional):
2(-7) - 4 = -18
-14 - 4 = -18
-18 = -18 so this is correct
If you're confused about any of these steps, just let me know and I'll try to clear it up for you! :)
First find volume of rectangular prism
Area of front side time length
9*6*11 = 594
Next find volume of semi-circular roof
Area of semi-circle times length
0.5*pi*(4.5)^2 * 11 = 111.375*pi = 349.89
Total Volume = 594 + 349.89 = 943.89 = 944
