Pyetja

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

  1. y=(x+1)2(x1)y=(x+1)^2(x-1)
  2. y=(x+2)(x1)2y=(x+2)(x-1)^2
  3. y=(2x)(x+1)2y=(2-x)(x+1)^2
  4. y=(x2)(x+1)2y=(x-2)(x+1)^2
  5. y=x2(x+2)y=x^2(x+2)
  6. y=(x1)2xy=(x-1)^2x
  7. y=(1x)2(3+x)y=(1-x)^2(3+x)
  8. y=(x1)2(3x)y=(x-1)^2(3-x)
  9. y=x2(2x)y=x^2(2-x)
  10. y=x2(x2)y=x^2(x-2)
