Find the Vertex Point

Give the vertex of the equation.

• (-5, -42)

• (-5, 8)

• (-10, -33)

• (5, 8)

Find the vertex of
f(x) = -x² - 4x + 12.

• (-2, 16)

• (2, 0)

• (2, 4)

• (-2, 4)

• 2

• -2

• 1

• -1

Knowing the axis of symmetry is x=4, what is the vertex in the equation \(y=-2x^2+16x-12\) ?

• (4, -12)

• (4, 20)

• (4, 84)

• (4, 116)

What's the x value of the vertex of y = 3x² - 6x + 4 ?

• x=1

• x=-6

• x=2

• x=-1

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
