Arrange the parabolas with respect tonthe postion of their vertices from left to right
agasfer [191]

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

A question on notation: Does sine inverse have an exponent? If not, why is there a negative one there? If so, why can't you just
NNADVOKAT [17]

Answer:

Step-by-step explanation:

When you write

          -1

y = sin    x, the "-1" is not an exponent, but rather an indication of "inverse function."

          -1

y = sin    x      can also be written as     y = arcsin x.

No exponentiation here, and no division here.

Bad White [126]
Convert 2/5 to a decimal and you get .4, or 40%. 40% of the band members also sing, so yes, the band has the same number of string instrument players and singers.
