Find the axis of symmetry:

y = -1/12 (x - 6)² + 4

• x = -6

• y = 4

• x = 6

• y = -4

Write in standard form:

y = 3(x - 2)(x + 5)

What is the effect on the graph of the equation y = x² - 3 when it is changed to y = x² + 6?

• The graph translates up.

• The graph changes from opening downward to opening upward.

• The graph narrows.

• The graph translates down.
