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

y = x2 + 2x -1

y = (x - 4)2 + 1

y = 3x2 + 4x - 2

What could be

the equation of

this graph?

y = 2x2 -4x + 3

y = (x + 1)(x + 3)

y = -(x - 2)2 + 1

y = -3(x - 1)2 + 2

What is the equation of this graph?

What is the equation

of this graph?

y = -(x - 2)2

y = 4x2 + 2x - 2

y = 2(x - 1)(x + 1)

y = x2 - 4x - 5

y = (x - 3)2 + 4

y = (x - 3)2 - 4

y = (x - 4)2 + 3

y = (x + 3)2 - 4

What is the equation of

this graph?

Write y = (x - 4)(x + 3) in standard form

y = x2 + 7x - 12

y = x2 - x - 12

y = x2 + x - 12

y = x2 - x + 12

Write y = 2(x - 2)2 -7 in standard form.

y = x2 - 4x - 3

y = 2x2 - 8x + 1

y = 2x2 - 8x - 3

y = 2x2 - 8x - 1

Determine whether y = 2(x - 5)2 + 1 has a minimum

or a maximum value.  Then find the minimum or

maximum.

Minimum, y = 1

Maximum, y = 1

Minimum, x = 5

Maximum, x = 5

Determine if y = -x2 - 4x + 5 has a minimum or

maximum.  Then find the minimum or maximum.

Minimum, y = 5

Maximum, y = 12

Maximum, y = 9

Minimum, y = 1
