Answer:
Step-by-step explanation:
part A. 
It's a decreasing exponential function. 
A relationship could be: Tom has 3 cookies. Each day, he eats half of the cookies left from the previous day.
part B.
y-intercept is the number of cookies he starts with, or 3. The rate that the cookies is decreasing is 1/2.
 
        
                    
             
        
        
        
5/6. 15 and 18 both have a common denominator of 3 (3*5 & 3*6). So if you do (15/3)/(18/3) you will get 5/6
