Describe what the graph of interval [-4,10] looks like.
What does this mean?
I think it means you have not provided enough information. [-4,10] would be a single point on a graph. For an interval you would need at least two points.
That said, its possible that your teacher(s) intend that [-4,10] mean something else besides a single point; what that is I cannot even guess.
