Which statement about a function is not true? Each input has exactly one output. The input value can always be any number. The output value is determined by the input value. The input value and output value cannot be the same number.

    I would say the first one if we have f(x)=sqrt(x) and input 4 for x, we get two answers -2, and 2

    actually, its a requirement of a function that each input should have exactly one output.

    Right! Which is why sqrt(x) graphed is only half a parabola.

    if i take an identity function, f(x) = x and you take any number as input 'x' you get same number as output which makes the last statement false that input and output cannot be same!
