726 times 5 is...
726 x 5 = 3630
        
             
        
        
        
A) the posible roots of the function f(x)=x⁴-3x³-5x²+21x+22 are: 
=-1,+1,-2,+2,-11,+11,-22+22.
b)
one zero of the funtion can be: x=-1 ⇒y=0  
 (-1,0)c)
other zero of the funtion is: x=-2 ⇒y=0
  (-2,0)d)
if x=0 then y=22   
(0,22)
e) In the file is the graph. 
 
        
        
        
Minus the 21 from the other side of the equation making it 7x=-21 then u divide the 7 from the x to the -21 resulting in x=-3
        
                    
             
        
        
        
1. 9 is the mode
2. 17.7 is the mean
3. 25.5 is the median
4. mean > median
5. 28 is the range
