How do you determine the x-coordinate of the vertex from the vertex form y = 3(x + 2)^2 - 27?

• Set x + 2 to 0

• Set x + 2 to 1

• Set x - 2 to 1

• Set x - 2 to 0

What is the y-coordinate of the vertex for the equation y = 3(x + 2)^2 - 27?

• -27

• 3

• -2

• 0

For the equation y = -2(x - 5)^2 + 10, what is the x-coordinate of the vertex?

• -10

• -5

• 10

• 5

In the equation y = -2(x - 5)^2 + 10, why is the parabola downward opening?

• Because the coefficient of x is negative

• Because the coefficient of x^2 is negative

• Because the constant term is positive

• Because the constant term is negative
