Question

Функция задана формулой y = x * (3 - x). если x = -2 , то y = -3 * (3-(-3)) = -1 * 6 = ______________ если x = -2, то y = -2 * (3-(-2)) = __________ если x =3, то y = ___________ если x = 7, то y = __________

Answer 1

1) первое неверно
2) =-2*5=-10
3) =3*0=0
4) =7*(-4)=-28

Answer 2

Let's calculate the values of y for different values of x using the given function y = x * (3 - x):

1. If x = -2: y = -2 * (3 - (-2)) y = -2 * (3 + 2) y = -2 * 5 y = -10

2. If x = -1: y = -1 * (3 - (-1)) y = -1 * (3 + 1) y = -1 * 4 y = -4

3. If x = 3: y = 3 * (3 - 3) y = 3 * (0) y = 0

4. If x = 7: y = 7 * (3 - 7) y = 7 * (-4) y = -28

So, the values of y for the given x-values are:

• y = -10 when x = -2
• y = -4 when x = -1
• y = 0 when x = 3
• y = -28 when x = 7
