Finding the Vertex Not in Standard Form

Identify the form of the quadratic function:
f(x)=(x+1)²-3

• Quadratic

• Standard

• Factored

• Vertex

What can we find easily in vertex form?

• vertex

• y-intercept

• zeros/x-intercepts

What information can I find from this form of the equation? f(x ) = (x - 5)2 + 8

• x-intercepts: x = 5 and x = 8

• y-intercept: y = 5

• vertex: (5, 8)

• vertex: (-5, 8)

What is the equation of this graph?

• f(x) = (x -5)² + 1

• f(x) = (x - 1)² - 5

• f(x) = (x + 1)² - 5

• f(x) = (x + 5)² +1
