Question

Arrange the parabolas with respect tonthe postion of their vertices from left to right

Answer 1

Answer:

The correct answer for this question is this one:

If the x position of the vertex for f(x) is k then : 

1. f(k) => 4x+3=k, x = (k-3)/4 = (k/4)-(3/4) 

2. x = k+3 

3. x = (k+1)/2 = (k/2)-(1/2) 

4. x = 2(k+2) = 2k+4 

5. x = k+7 

6. x = k-3 

7. x = k-2 

So the order depends on the original position of the vertex k, e.g for k=0 the positions would be: 

1. -3/4 

2. 3 

3. -1/2 

4. 4 

5. 7 

6. -3 

7. -2 

So, therefore, the order would be 6 7 1 3 2 4 5
