Identify a function which has the following three properties: it has at least one minimum or maximum, it is an increasing function and the range of this function is the set of all nonnegative numbers.
\(f(x) = 2x - 2\),
\(x\in [ 1,+\infty )\)
\(f(x) = 2x + 2\),
\(x\in (-1,+\infty )\)
\(f(x) = -2x + 2\),
\(x\in (-\infty ,1] \)
\(f(x) = -2x - 2\),
\(x\in \mathbb{R}\)
