1. The graph of y=f(x) is a parabola whose vertex is at (1, -2). The graph of y=f(x-3) is also a parabola. Where is the vertex of the graph of y=f(x-3)?
2. The graph of y=f(x) has the line x=5 as an axis of symmetry. The graph also passes through the point (8, -7). Find another point that must lie on the graph of y=f(x)
