  = 7
Number of birds, Jean saw on the third one  = 7
 = 7
So,
average number  of birds Jean saw each day = 
Therefore,
Jaw saw an average of 6 birds each day
 
        
             
        
        
        
The functions have complex roots from the image are
 Functions (b) and (d). This is further explained below.
<h3>What is Function?</h3>
Generally, Function is simply defined as a connection between two or more variables that may be expressed mathematically.
In conclusion,  Functions with graphs that never touch or cross the x-axis are said to have complicated roots, not real ones.
