Using your calculator, graph y = -3x² + 6x - 5 and identify the max or min.

• Max: (1, -2)
• Min: (1, -2)
• Max: (-2, 1)
• Min: (-2, 1)

Using your calculator, graph y = 2x² + 4x - 3 and identify the max or min.

• Max: (-1, -5)
• Min: (-1, -5)
• Max: (-5, -1)
• Min: (-5, -1)

What are the Zeroes for this graph?

• x= 0 and x= -4
