Partner up. In a group of 2 or 3 discuss the following graph and then designate one person to type a agreed upon description of the graph for the group. Include the vertex of the parabola in your description.

$$f\left(x\right)\ =2x^2+1$$  

Partner up. In a group of 2 or 3 discuss the following graph and then designate one person to type a agreed upon description of the graph for the group. Include the vertex of the parabola and the axis of symmetry in your description.

$$f\left(x\right)\ =\left(x+3\right)^2-4$$  

Partner up. In a group of 2 or 3 discuss the following graph and then designate one person to type a agreed upon description of the graph for the group. Include the vertex of the parabola and the axis of symmetry in your description.

$$f\left(x\right)\ =x^2-4x+4$$  

Your turn:  Find the vertex of the parabola.

$$f\left(x\right)\ =\ x^2-4x+9$$
