What is the vertex of this parabola?

• (−1, 3)

• (−3, 11)

• (−2, 5)

• (0, 5)

What is the vertex of this function?

• (0, -3)

To find the vertex of a quadratic in standard form, you ​ (a)   and ​ (b)   . Then you ​ (c)   the value back into the ​ (d)   to find the ​ (e)   coordinate of the vertex.

• take the opposite of b

• divide it by 2

• substitute

• equation

• y

• x

• take the opposite of c

• multiply it by 5

The vertex of parabola y = - 2x² - 4x + 1 is

• (1, 3)

• (- 1, 5)

Find the Vertex: y= -5x² -20x - 26

• (-2, -6)

• (2, 6)

• (6,2)

• (3, 6)

Given: y = 2(x - 5) + 6, the vertex is
