Answer:
The graph of given function open upward.
Step-by-step explanation:
The given equation is
[tex]y=3|x|-8[/tex] ....(1)
The general form of an absolute function is
[tex]f(x)=a|x|+b[/tex] .....(2)
If a>0, then the graph of function open up and if a<0, then the graph of function open down.
On comparing (1) and (2), we get
[tex]a=3,b=-8[/tex]
Since a=3>0, therefore the graph of given function open upward.
