Hey All ^_^

I thought a thread like this is missing on the forum ^_^
 
I am doing this course on Khan Academy. It's Computer Animation Programming. And there is this question I don't understand.
What do you think?

The answer is there but I don't understand it :p

Where is "the blue surface around the points" exactly?

I assume the blue dots are heat sources and the peanut shape the maximum distance from those dots where a temperature of 100 degrees exists. In that case, everything outside the peanut shape is below 100 degrees. The rest is equal to 100 degrees I guess. In real life the dots would need a higher temperature than 100 degrees to compensate the dissipation of heat.
 
Sorry that nobody helped you earlier. I assume this is too little too late.

The blue line that looks like a peanut is a boundary line at 100 degrees. The two blue dots inside it would represent the heat sources. Any x within the boundary is above 100 degrees, outside the boundary is below 100 degrees, and on the line would be equal to 100 degrees.
