Identify the form of the quadratic function:

f(x) = x² - 9x + 11

• Vertex

• Standard

• Factored

What information can I find from this form of the equation?

f(x ) = (x - 9)(x - 10)

• x-intercepts: x = 9 and x = 10

• y-intercept: y = 19

• vertex: (9, 10)

What information can I find from this form of the equation?

f(x ) = x² + 8x + 11

• x-intercepts: x = 8 and x = 11

• y-intercept: y = 11

• vertex: (8, 11)
