Question

F(x) = |ax-b|+c|x| for all x belong to r assumes its minimum value only at one point of

Answer 1

a not equals c is the answer maybe

Answer 2

The function f(x) = |px – q| + r|x|, x , where p > 0, q > 0, r > 0,

assume its minimum value only at one point.

There are several ways to obtain results and thus it bring forth most elements taken by the square px and nature of the function is f(x).
