Question

Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum

Answer 1

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)
