Nothing to "solve" here. Just graph this absolute value function.
Note that if x=2 we get y = -4. Thus, (2,-4) is the vertex. Plot this point.
Now, starting from (2, -4), draw a line at a 45 degree angle to the horizontal.
Then draw a corresponding line on the other side of the y-axis. You're done!
Answer:
[y]=-18 so y belongs to (-18,-17)
Step-by-step explanation:
You just have to use the squares one to factor this and this is what I got.
