Question

помогите сделать 7.7, дам 100 баллов ​

Answer 1

Ответ:

1) y = x^2 - 4x + 5.25\) при (x = -1):

y = (-1)^2 - 4(-1) + 5.25 = 1 + 4 + 5.25 = 10.25

2) y = -x^2 - x + 3.75\ при x = -5

\[y = -(-5)^2 - (-5) + 3.75 = -25 + 5 + 3.75 = -16.25

3) y = x^2 + 6x + 6\) при \(x = -6

\[y = (-6)^2 + 6(-6) + 6 = 36 - 36 + 6 = 6

4) y = -x^2 - 8x - 18.5\) при \(x = 3

y = -3^2 - 8(3) - 18.5 = -9 - 24 - 18.5 = -51.5
