Graphing Horizontal Parabolas

The axis of symmetry line passes through which point?

• y-intercept

• any random point

• vertex

• symmetrical point for the vertex

The graph of a quadratic function is called a

• Parabola

• Vertex

• Axis of Symmetry 

• Vertex Form

In vertex form, what effect does the h have on the graph?

• Translates Up/Down

• Translates Left/Right

• Narrows/Widens Parabola

• Flips it

Describe the horizontal shift for

y = 3(x + 4)² - 1

• shifts 3 left

• shifts 4 left

• shifts 4 right

• shifts 1 left

• D

Match the description to its equation.
Moves up 2
Moves left 4

• A

• B

• C

• D

If we have the equation y=ax²+bx+c, how can we can find the x-coordinate of the vertex?

• -a

• -b/a

• b/2a

• -b/2a

What is the significance of the 'h' value in the vertex form of a quadratic function?

• The 'h' value represents the horizontal shift of the parabola.

• The 'h' value determines the vertical stretch of the parabola.

• The 'h' value represents the axis of symmetry of the parabola.

• The 'h' value indicates the y-intercept of the parabola.

Identify the vertex and whether the graph is concave up or concave down.

• (5, 2); concave up

• (5, 2); concave down

• (-5, 2); concave up

• (-5, 2); concave down
