Pyetja

Skico vijat e mëposhtme dhe trego qartë pikat e prerjes me boshtet:

  1. y=(x+1)(x+2)(x+3)(x+4)y=(x+1)(x+2)(x+3)(x+4)
  2. y=x(x−1)(x+3)(x−2)y=x(x-1)(x+3)(x-2)
  3. y=x(x+1)2(x+2)y=x(x+1)^2(x+2)
  4. y=(2x−1)(x+2)(x−1)(x−2)y=(2x-1)(x+2)(x-1)(x-2)
  5. y=x2(4x+1)(4x−1)y=x^2(4x+1)(4x-1)
  6. y=−(x−4)2(x−2)2y=-(x-4)^2(x-2)^2
  7. y=(x−3)2(x+1)2y=(x-3)^2(x+1)^2
  8. y=(x+2)3(x−3)y=(x+2)^3(x-3)
  9. y=−(2x−1)3(x+5)y=-(2x-1)^3(x+5)
  10. y=(x+4)4y=(x+4)^4
