Question

Which direction would the graph of y=3|x|-8 open

Answer 1

The graph would open at the down at the bottom

Answer 2

The graph of given function open upward.

Explanation:

The given equation is

`y=3|x|-8` ....(1)

The general form of an absolute function is

`f(x)=a|x|+b` .....(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

`a=3,b=-8`

Since a=3>0, therefore the graph of given function open upward.
