Optima Learn · Accepted Answer

Step 1 We are given the curve y x - 1 x 1 First, express this piecewise. There are critical points at and . - For , So - For , So - For , So Thus, piecewise y -2x x leq -1 2 -1 leq x leq 1 2x x geq 1 We need the shortest distance from . Since , we consider . At , . But our point is . We can compute
