The vertex of this parabola is at (2, -4). Which of the following could be its equation?

A. y = 2(x - 2)2 + 4

B. x = 2(y + 4)2 + 2

C. x = 2(y - 4)2 + 2

D. y = 2(x - 2)2 - 4

The answer to your question is letter B

Step-by-step explanation:

Data

Vertex = (2, -4)

Process

From the image we know that it is a horizontal parabola that opens to the right so the equation must be

                         (y - k)² = 4p(x - h)

Let 4p be 1

- Substitution

                         (y + 4)² = (x - 2)

- Solve for  x

                        (y + 4)² = x - 2

- Result

                        x = (y + 4)² + 2            

The answer is letter B, because of the signs.              

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
