Hello :
F(x)= x^2-4/2x^3-32x
F exist if : 2x^3-32x ≠ 0
2x^3-32x = 0
2x (x²-16)=0
2x(x-4)(x+4)=0
2x=0 or x-4=0 or x+4 =0
x=0 or x=4 or x= -4
the domain is : D= ] -∞ ; -4[ ∪ ] -4 ; 0[∪ ] 0 ; 4[ ∪ ]4 ; + ∞[

X+ y + z = -3 3y - Z = 4 2x- y - 2z = -5

snow_lady [41]

Answer:

(-3, 1, -1)

Step-by-step explanation:

x + y + z = -3 --> (1)
3y - z = 4 --> (2)
2x - y - 2z = -5 --> (3)

Add up (1) and (2)

x + 3y + y + z - z = -3 + 4 ⇒ x + 4y = 1 --> (4)

Double (2) and subtract from (3)

2x - y - 2z - 2(3y - z) = -5 - 2(4) ⇒ 2x - y - 2z - 6y + 2z = -5 - 8
2x - 7y = -13 --> (5)

Double (4) and subtract (5)

2(x + 4y) - 2x + 7y = 2 + 13 ⇒ 2x + 8y - 2x + 7y = 15 ⇒ 15y = 15 ⇒ y = 1

Finding x

x + 4(1) = 1 ⇒ x = 1 - 4 ⇒ x = -3

Finding z

-3 + 1 + z = -3 ⇒ z = -1

So the answer is:

(-3, 1, -1)
