Finding the Vertex of the Graph

Which equation has a vertex of (-3, 4)?

• y = (x + 3)² + 4

• y = (x + 3)² - 4

• y = (x - 3)² + 4

• y = (x - 3)² - 4

Find the vertex: f\left(x\right)=x^2+8x+7

• (-4, 23)

• (-9, 4)

• (-4, -9)

• (4, 9)

Find the vertex:

f(x) = -2x² + 4x + 3

• (0, 3)

• (-1, 5)

• (1, 5)

• (1, -5)

What does "vertex" mean?

• The highest or lowest coordinate point of a quadratic function

• An x-intercept of a quadratic function, AKA a "zero"

• Any coordinate point on a quadratic function

• The process of completing the square

What is the vertex of f\left(x\right)=\left(x+6\right)^2+8?

• (-6, 8)

• (6, -8)

• (0, 0)

• (-6,-8)

• (5, -4)

• (-5, -4)

• (5, 4)

• (15, -4)

What is the vertex of the parabola: y=2(x-3)²+4

• (3,4)

• (-3,4)

• (3, -4)

• (-3,-4)

If given the equation
y = 3(x + 5)² - 4,
what is the vertex of the parabola?

• (5, -4)

• (-5, -4)

• (-15, -4)

• (15, -4)

If given the equation y = 3(x + 5)² - 4, what is the vertex of the parabola?

• (5, -4)

• (-5, -4)

• (-15, -4)

• (15, -4)

Identify the vertex and whether the graph opens up or down.

• (5, 2); opens up

• (5, 2); opens down

• (-5, 2); opens up

• (-5, 2); opens down
