Quadratic equations take the shape of a _______ when graphed.

• parabola

• straight line

• snaked line

• elliptical

The highest or lowest point on a quadratic is called the...

• Max
• Vertex
• Axis of Symmetry
• Intercept

The axis of symmetry line passes through which point?

• y-intercept

• any random point

• vertex

• symmetrical point for the vertex

What is the green dashed line called?

• roots or x-intercepts

• parabola

• axis of symmetry

• y intercept

Does this graph have a maximum or a minimum?

• maximum

• minimum

• I am not sure.

• neither

Does this parabola have a minimum or maximum and what is its value?

• minimum: 2

• maximum: 2

• minimum: 5

• maximum: 5

Use the picture to find the vertex and axis of symmetry:

• Vertex (3,8) Axis x = 3

• Vertex (3,8) Axis y = 3

• Vertex (8,3) Axis x = 3

• Vertex (8,3) Axis y = 3

Use the graph to determine the X-intercepts:

• (-1,0) and (-3,0)

• (1,0) and (3,0)

• (0,1) and (0,3)

• (0,-1) and (0,-3)

What is the vertex of the quadratic function:

f(x) = x² - 6x + 11

Hint: Use Desmos

• (3,2)

• (-3,-2)

• (-3,2)

• (3,-2)

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5
• x = 20 and x = -9
• x = 4 and x = 5
• x = -4 and x = 5
