Answer: below
Domain: (0,1,2)
Range: (15,18,21)
Step-by-step explanation: Domain is possible input values while range is possible output values. So if it is for 0 minutes it will be 15 degrees, 1 minute 18 degrees because 15 + 3( 0 or 1 or 2 etc.). And for 2 minutes it would be 21 degrees. This could go on forever in a graph but I picked 3 simple points, 0, 1, and 2 minutes.
Hope this helps!
