Given $f(x)=|x+2|$ on $R$
$\Rightarrow f(x) \geq 0$ for all $x \in R$
So, the minimum value of $f(x)$ is 0, which attains at $x=-2$
Hence, $f(x)=|x+2|$ does not have the maximum value.
Find the maximum and the minimum values, if any, without using derivaties of the following functions: f (x) = |x + 2| on R
