Does the graph have a minimum or maximum?

• minimum

• maximum

Which of the following is the vertex of the graph?

• (2, 0)

• (-2, 0)

• (0, 4)

• (-1, 3)

Find the vertex of
y = 4x² + 4x + 4
Use the equation in the picture!

• (0, 0)

• (-0.5, 7)

• (0.5, 4)

• (0.375, 6.0625)

The turning point of the parabola is called the ​ (a)   . When the parabola opens up, then we say that it has a ​ (b)   value. Another word for X-intercepts is ​ (c)   . The invisible line that cuts the parabola in ​ (d)   is called the ​ (e)   .

• vertex

• minimum

• zeros

• half

• axis of symmetry.

• k

• minimum

• maximum

Select the correct drop-down items to make the sentences true. The parabola has a vertex of ​ ​ (a)   . The axis of symmetry of the graph is ​ (b)   . The graph has ​ (c)   zero(s).

• (-3, 0)

• 1

• 2

• 0

• (0, -3)

In the equation of a parabola, d is the distance from the ​ (a)   to the ​ (b)   .

• vertex

• focus

• parabola

Match the following.

• when a > 0

• parabola opens down

• when a < 0

• y - intercept

• axis of symmetry

• vertex

• (0 , c)

• parabola opens up

Given a parabola with a vertex at (4,3) and a directrix of y=1, write the equation of the parabola.
