Answer

Please see the graph.

Work Step by Step

$y < (x-2)^2+1$ $y=(x-2)^2+1$ $y=(x-2)(x-2)+1$ $y=x*x+x*-2+x*-2+(-2)(-2)+1$ $y=x^2-2x-2x+4+1$ $y=x^2-4x+5$ $a=1$, $b=-4$, $c=5$ Axis of symmetry is at $x=-b/2a$ $x=-b/2a$ $x=-(-4)/2*1$ $x=4/2$ $x=2$ $y < (x-2)^2+1$ $y < (2-2)^2+1$ $y < 0^2 +1$ $y< 0+1$ $y < 1$ For $x=2$, as long as $y <1$, we shade the region with that point. (Example: $y=0$, and we would shade the region with the point $(2,1)$.)
