Function Behavior of Quadratics

The point shown in the graph is an example of what?

• root

• maximum

• vertex

• y-intercept

How many zero(s) does this function have?

• 0

• 1

• 2

• 3

The highlighted blue point is what you can use to identify the graph's

• axis of symmetry

• y-intercept

• vertex

• maximum

• minimum

Answer explanation

The point does not cross the y-axis so it is not a y-intercept. The point is also not a minimum because it's the highest point in the graph. This point can be used to find the axis of symmetry (x = x-coordinate of the vertex), the maximum (y-coordinate of the vertex), and the point, itself, IS the vertex.

What is/are the zeros of the graph?

• (-3, 1)

• (-4, 0)

• (-2, 0)

• (0, -4)

• (0, -2)
