I am pretty sure its B (minimum at -1, -4) because that would be were the first point would be at. The Graphing of this equation would be a "upside down u" shape.
-18 + x = -11
Let's add 18 to both sides
x = 7
1. 30.25
2. 81
3. Square Root of 2 plus 1, Negative Square Root of 2 plus 1.
4. Square Root of 57 minus 3, Negative Square root of 57 minus 3
5. Square Root of 53.25 minus 11, Negative Square root of 53.25 minus 11
A) K=1/2C-3
K+C=18
Hope this helps! Have a great day :)
