Question

A = 0,5 - lx - 3,5l

B = - l1,4 - xl - 2

Answer 1

\(A=0,5-\left|x-3,5\right|=\) \(\left[{}\begin{matrix}0,5-x+3,5\left(x\ge3,5\right)\\0,5+x-3,5\left(x< 3,5\right)\end{matrix}\right.\)

\(=\left[{}\begin{matrix}-x+4\left(x\ge3,5\right)\\x-3\left(x< 3,5\right)\end{matrix}\right.\)

\(B=-\left|1,4-x\right|-2\)

\(=\left[{}\begin{matrix}-1,4+x-2\left(x\le1,4\right)\\1,4-x-2\left(x>1,4\right)\end{matrix}\right.\)\(=\left[{}\begin{matrix}x-3,4\left(x\le1,4\right)\\-x-0,6\left(x>1,4\right)\end{matrix}\right.\)
