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)   .
