I don't know can u explain
Your answer: -0.8
first you would add all of your temperatures together which would give you -5.6
then you would divide -5.6 by 7 because u have 7 numbers
which would give you your answer!
hope this helps, good luck!
I can't help you with your graphing tool. With my graphing tool, the graph looks like this.
The vertex is at (-4, -1), and it goes through the point (-3, 1).
