What is the range of h?

The range of h is 10.

The range is the difference between the highest and lowest y-values for each point on the graph.
The y-values for this graph are {-4,-2,2,4,6}
To find the range you have to solve for the difference between the highest(6) and lowest(-4) numbers.

To find the difference, count how many spaces are between the numbers -4 and 6 on the graph, and you should count 10.

I hope this helped! If you have any questions about anything I mentioned above please feel free to comment on my answer with your questions and I’ll try to get back to you!
