Identify the vertex and whether the graph opens up or down.

• (5, 2); opens up

• (5, 2); opens down

• (-5, 2); opens up

• (-5, 2); opens down

What is the green dashed line called?

• roots or x-intercepts

• parabola

• line of symmetry

• line of dashes

Write the equation of a parabola that has shifted 4 units to the right, 5 units down, and has flipped over the x-axis.

• y = - (x - 5)² + 4

• y = - (x - 4)² - 5

• y = - (x + 4)² - 5

• y = - (x + 5)² + 4

What is the equation of this graph?

• y = (x -5)² + 1

• y = (x - 1)² - 5

• y = (x + 1)² - 5

• y = (x + 5)² +1
