range of f(x)
Let the range of the function $f:\mathbb{R}\rightarrow \mathbb{R}$ and $f(x) = | x-1| + |x - a| + | x| + |x+1| + |x+ 2a - 21 |$ given by $\left[\alpha,\infty \right)$ where $a$ being a real parameter . Then find the number of integral values of $a$ for which there is exactly one $x_{0}\in\mathbb{R}$...
