The vertex is the _______ because a>0 in this quadratic equation.

Match the following attributes to their coordinates or equation.

• Maximum

• x=3

• Vertex

• (0,-5)

• y-intercept

• (3,4)

• axis of symmetry

• (1,0) and (5,0)

• x-intercepts

• Vertex

Match the following coordinate or equation to its special attribute.

• Is the x value of the vertex.

• Axis of Symmetry

• Crosses the x-axis

• Vertex

• Crosses the y-axis

• y-intercept

• Graph opens up

• x-intercepts

• Minimum

• a>0

Graph the equation y=x²+4x+4.

Hint: the vertex is (-4,0) and the y-intercept is (0,4)
