That is incorrect. The equation of the line of symmetry is x = -b as per you illustrated example.

The sketch would look like this (see below). Ignore any part of the curve to the left of the origin.

The graph is not defined for anything less than 1 or greater than 7.... draw a horizontal line at those points, notice they never intersect the curve.
