Exercise 36 Page 207

Find the symmetric point to the given point across the axis of symmetry.

Practice makes perfect

We are given the vertex and one point that lies on a parabola. To draw its graph, recall that the axis of symmetry is the vertical line through the vertex. Since the vertex is ( 2,3), the axis of symmetry is the line x= 2. Let's plot the vertex, the given point (6,9), and the point symmetric across the axis of symmetry.

Finally, let's connect the three points with a smooth curve. Do not use a straight edge for this part!
