Question 1013877
First graph the boundary equation:

y = |x – 3|

x | y
0 | 3
3 | 0
6 | 3

Draw it dotted since y is strictly greater than:

{{{graph(400,280,-2,8,-2,5,abs(x-3)*sqrt(sin(9x))/sqrt(sin(9x)))}}}

Since y is "strictly greater than" we shade the region above the dotted
V-shaped graph.

{{{drawing(400,280,-2,8,-2,5,graph(400,280,-2,8,-2,5,abs(x-3)*sqrt(sin(9x))/sqrt(sin(9x)),18,17,16,15,y>abs(x-3)+.1),
graph(400,280,-2,8,-2,5)
