Question

Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum
value. Select the TWO correct answers.
y = x2 + 4x – 10
–
A)
The vertex form is y = (x – 6)2 + 2.
B)
The vertex form is y= 4x + 2)2 – 10.
C)
The vertex form is y = -(x – 2)2 – 6.
D)
The vertex is a minimum value at point (-6,2).
E)
The vertex is a maximum value at point (2.-6).

    Answer:

    Step-by-step explanation:

    The equation as written doesn’t work. Are you sure it is y = x² + 4x – 10, and not

    y = -x² + 4x – 10 ?

    y = -(x² – 4x) – 10

    y = -(x² – 4x + 2²) + 2² – 10

    y = -(x-2)² – 6

    the vertex is a maximum at (2,-6)
