A lattice point is a point whose coordinates are both integers. How many lattice points are on the boundary or inside the region bounded by the x-axis, the line x=4 and the curve y=2\sqrt{x}?

You don't specify  a leftmost  bound but if  we  take it  as  the   line  x  =1, we have  9 lattice points
