Give an example to show that the product of two one-to-one function is not necessarily a one-to-one function.

  • Precalculus -

    y=x
    y=-x
    y^2 = -x^2

  • Precalculus -

    Sorry I don't understand y^2=-x^2 ??
    Shouldn't it be:(y)(y)=(x)(-x)
    y^2 = -x ??

  • Precalculus -

    (x)(-x) = -x^2
