If (f:\mathbb{R}\to\mathbb{R}), (f(x)=(x-1)^2), on which interval will it not be one-one?

Answer and explanation

Correct answer: \([0,2]\) / ([0,2])

Step 1: The vertex of ((x-1)^2) is at (x=1). Step 2: The interval ([0,2]) contains points on both sides of the vertex, such as (0) and (2), both giving value (1). Step 3: If an interval contains points equally placed around the vertex, a quadratic is not one-one.
