answer:

y = 3x² + 6x + 1

Step-by-step explanation:

y = a(x - h)² + k

(h,k) is (-1,-2)

y = a(x-(-1))² - 2

y = a(x + 1)² - 2

When x = 0, y = 1

1 = a(0 + 1)² - 2

3 = a

y = 3(x + 1)² - 2

y = 3(x² + 2x + 1) - 2

y = 3x² + 6x + 3 - 2

y = 3x² + 6x + 1

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5
