# Without using derivative find the maximum or minimum value of f(x) = |x+5| + 3

Jitender Singh IIT Delhi
7 years ago
Ans:
$f(x) = |x+5| + 3$
$f(x) = x+8, x \geq -5$
$f(x) = -x-2, x < -5$
If you plot the graph of this function, you will see that the minimun value of f(x) is ‘3’ & maximum value is infinite.
Thanks & Regards
