The Integers Are Positive They Are Not Negative Numbers. If It Was Negative It Would Be -2,-3,-4. While If It's Positive It Should Be 0,1,2,3,4 And So On.
        
             
        
        
        
Answer:
vertex = (0, -4)
equation of the parabola:  
Step-by-step explanation:
Given:
- y-intercept of parabola: -4
- parabola passes through points: (-2, 8) and (1, -1)
Vertex form of a parabola:  
(where (h, k) is the vertex and  is some constant)
 is some constant)
Substitute point (0, -4) into the equation:

Substitute point (-2, 8) and  into the equation:
 into the equation:

Substitute point (1, -1) and  into the equation:
 into the equation:

Equate to find h:

Substitute found value of h into one of the equations to find a:

Substitute found values of h and a to find k:

Therefore, the equation of the parabola in vertex form is:

So the vertex of the parabola is (0, -4)
 
        
                    
             
        
        
        
Answer:
QM = 21
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, then
QM = PQ = 21
 
        
             
        
        
        
45 because, the short side is half of the big size. That might be correct. But I'm almost positive
