Express $y={{x}^{2}}-8x+17$ in the form of $y={{(x-h)}^{2}}+k$. Hence, state

the maximum or minimum point of the function and the value of $x$ where it occurs

the equation of the line of symmetry of the graph.

Sketch the graph and indicate clearly the turning point and cutting point(s) on the axes.
