Τhe function ƒ, It is truly descending to (-∞, 2) and vertically increasing to [2, + ∞),
Presents for x = 2 minimum, ƒ (2) = -1.
In addition, the graph of ƒ is a parable that: Has a symmetry axis x = 2 and Intersects the x'x axis at the cut-off points 1 and 3 respectively, which are the roots of the truncated , and the y'y axis at the ordinate 3.
