When λ = 0, the penalty term in lasso regression has no effect and thus it produces the same coefficient estimates as least squares.

WebSo the smallest y can possibly be is y = k, and this smallest value will happen when the squared part, x − h, equals zero. And the squared part is zero when x − h = 0, or when x = h. The same reasoning works, with k being the largest value and the squared part always subtracting from it, for upside-down parabolas.
