Zero (+)

Vertex

Zero(-)

Given the equation

y = 3(x + 5)² - 4, the vertex is (​ ​ (a)   ). it has a ​ (b)   value, the equation of axis of symmetry is ​ (c)   , and the parabola opens ​ (d)  

• -5,-4
• 5,4
• 3,5
• -4,-5
• Minimum
• Maximum
• x=-5
• y=-5
• up
• down

​ ​ Select all correct answers that match with the given graph.

• Vertex at (3,0)

• Vertex at (0,3)

• No Solutions

• One Solution

• Vertex

  (0.5,-9)

• Axis of Symmetry

  x=-0.5

• Two Zeros

• Maximum Value at -9

• One of the zeros is

  (-2,0)

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)   .
