Answer:

Step-by-step explanation:
- Apply the distributed property, so it now looks like this: -3n + -18 + 10 = -9
- Combine like terms: -3n + -8 = -9
- Simplify: -3n - 8 = -9
- Add 8 to each side, so it now looks like this: -3n = -1
- Divide each side by -3 to cancel out the -3 next to n. It should now look like this: n = 1/3

(650 + 550 + 380 + 720 + 710 + 550) / 6 = 3560/6 = 593.3
We have to use these points to verify which of the equations is correct.
When we use points in 3rd equation:
( -2, 18) : y= 3 * (-2)² - 2* (-2)+2= 12 + 4 + 2 = 18 (true)
( 0, 2 ) : y= 3* 0² - 2 * 0 + 2 = 2 (true)
( 4 , 42 ): y= 3 *4²- 2 *4+ 2 = 48 - 8 + 2 = 42 (true)
The answer is: C) y=3 x² - 2 x + 2
