Question 1 of 10 2 Points
The standard form of the equation of a parabola is y = 7x2 + 14x + 4.
What is the vertex form of the equation?
A. y = 7(x + 1)2-3
B. y= 7(x + 2)2-3
c. y= 7(x + 1)2 + 3
D. y= 7(x + 2)2 + 3
SUBMIT

A. y = 7(x + 1)²-3

Step-by-step explanation:

Parabola:

Putting into vertex form, remember that:

In this question:

, to put into this format:

We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then

Vertex form:

So the correct answer is:

A. y = 7(x + 1)²-3

the answer is stop cheating on things stoopid
