Identify the vertex of this quadratic graph.

Identify the y-intercept of this quadratic graph.

Identify the zeroes of this quadratic graph.

If you want to know the y-intercept value of a graph, set the ​ (a)   ​to ​ (b)   and evalute

• x value
• 0

• 1
• -1
• 2

If a quadratic has 2 solutions, it has ​ (a)   zeroes. If it has 1 solution, it only ​ (b)   the x-axis. (This is called a ​ (c)   root.) If it has ​ (d)   solutions, it never touches the x-axis.
