Understanding quadratic functions

What is the axis of symmetry for the quadratic function y = -2x^2 + 8x - 5?

• x = -2

• x = 5

• x = 0

• x = 2

What is the vertex of the parabola?

f(x) = 5(x-3)²+5

• (3,5)

• (-3,5)

• (3, -5)

• (-3,-5)

The graph of a quadratic function is shown on the grid. Which equations best represents the axis of symmetry?

HINT: A.O.S. runs through vertex

• y = 6

• x = 2

• y = 4

• x = 0

Identify the axis of symmetry

• x=-1

• y=-4

• x=1

• y=4

Is the vertex of the function a maximum or a minimum

 $y=-\left(x-4\right)^2+3$  

• maximum
  

• minimum

What is the vertex of this equation?

y = lx + 4l + 4

• (-4, 4)

• (-4, -4)

• (4, 4)

• (4, -4)

• There is a minimum at y = 3

• There is a maximum at y = 3

• There is a minimum at y = 5

• There is a maximum at y = 5.

What is the vertex of y= x² - 8x + 14 ?

• (2, 4)

• (−4, −2)

• (4, −2)

• (−2, 4)

What is the vertex?

• (0, - 1)
• (0, 0.5)
• (-1, 0)
• (0.5, 0)

The vertical line that divides your quadratic graph into two equal parts is called the (choose all that apply):

• line of symmetry

• axis of symmetry

• vertex

• foldline
