Step-by-step explanation:
The domain of the function is the range of x-values, which is -5 <= x <= 5. (D)
(16-x²)+(4-x) or (-x²+16)+(-x+4)
Combine like terms
(-x²+20-x) or (-x²-x+20)
I'm not 100 percent sure I think d

Answer:
7.9
4.2
9.3
17.8
Step-by-step explanation:

the square of 8 is 64 √63 is close to 64 so we can say it's 7.9 approximately
9. √18
the square of 4 is 16, √18 is greater than 16 so we can say it's 4.2 approximately
10. √87
the square of 9 is 81, √87 is greater than 81 so we can say the value of it is approximately 9.3
11. √319
the square of 18 is 324, √319 is smaller than 324 so we can say it's 17.8
