Answer:
-16
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Because in D, there no x-value that are repeating in the list.
For example A, the value 8 and -8 are being repeated twice, which makes this relation not a fuction.
Answer:
B
Step-by-step explanation:
use quadratic formula: (-b ±√b²-4ac) ÷ 2a
a = 10, b = -9, c = -6
![75-2(9-5)^2+2^3](https://tex.z-dn.net/?f=75-2%289-5%29%5E2%2B2%5E3)
First, solve the parentheses:
![75-2(4)^2+2^3](https://tex.z-dn.net/?f=75-2%284%29%5E2%2B2%5E3)
Next, the exponential terms
![75-2(16)+8](https://tex.z-dn.net/?f=75-2%2816%29%2B8)
Solve the multiplication:
![75-32+8](https://tex.z-dn.net/?f=75-32%2B8)
Add and subtract:
