  • The image displays a graph with a horizontal axis labeled with integer values, \(n\), ranging from at least negative three to positive two.
  • A vertical axis labeled \(u_n\) indicates the magnitude of the values.
  • Three distinct, upright vertical lines are drawn, each representing a non-zero value at a specific integer location on the horizontal axis.
  • The first vertical line is located at \(n=0\) and has a height of one.
  • The second vertical line is located at \(n=1\) and also has a height of one.
  • The third vertical line is located at \(n=2\) and also has a height of one.
  • For all other integer values of \(n\) shown on the axis (specifically \(n=-3, n=-2, n=-1\), and for \(n>2\)), no vertical line is present, implying a value of zero for \(u_n\).
