to be a function, every x has to have exactly one y, so there can't be the same number x twice wirh different y's
for all 
in [-3, 0], so 
is non-decreasing over this interval, and in particular we know right away that its minimum value must occur at 
.
From the plot, it's clear that on [-3, 0] we have 
. So
for some constant 
. Given that 
, we find that
so that on [-3, 0] we have
and
