Hi,
Could anyone please advise on this question?
I wonder if there is any other (simpler) way to solve this other than my approach.
I basically divided into four situations:
(1) 1-x>=0, y-1>=0
(2) 1-x>=0, y-1<0
(3) 1-x<0, y-1>=0
(4) 1-x<0, y-1<0
Then, I solved each equation with an algebra.
(1) y=x ; when 1>=x, y>=1
(2) y=-x+2 ; when 1>= x, y<1
(3) y=x ; when 1<x, y>=1
(4) y=-x+2 ; when 1<x, y<1
And then, I drew a graph for each situation.
I got the question right, but it took me like 7 minutes, so my approach definitely was a time sinkhole.
Does anyone know a better approach to solve this than mine? Would really appreciate your tips!
