The question is worded a bit strangely (in my opinion anyway), but I think your teacher wants you to describe how exponents work.
Let's say we had the expression 
The base is 5 as its the bottom most value (think of something like the base of a tree or building). The exponent is 3.
The exponent of 3 tells the reader to multiply the base 5 by itself 3 times like so

With larger exponents, it becomes more tedious to write out all the repeated multiplications, which is why many calculators have an exponent button to save time.
Answer:
15 feet
Step-by-step explanation:
525 = ½(30+40)h
525 = 35h
h = 525/35
h = 15 feet
You are describing where I live only that temperature is a bit low. I'm sorry to say it is neither one.
t_daily = t_average +/- 5
The highest temperature would be
t_daily = t_average + 5
t_daily = 1 + 5
t_daily = 6
================
The Lowest temperature would be
t_daily = t_average - 5
t_daily = 1 - 5
t_daily = - 4
Sounds about right for December.
When each x value has only one y value, the relation is a function
