Answer:

Bottom right graph.

See attachment.

Explanation:

Graph of the parent ceiling function f(x) = ⌈x⌉

The graph of the parent function has:

  • open dots at (x, x+1) → (0, 1), (1, 2), (2, 3), etc.
  • closed dots at (x, x) → (1, 1), (2, 2), (3, 3), etc.

Each segment is joined with a horizontal line (step).

The open dot means the value is not included, whereas the closed dot means the value is included.

Graph of the ceiling function f(x) = 1/2⌈x⌉

The y-values of the dots will be half those of the parent function.

So the graph of the function has:

  • open dots at (x, ¹/₂(x+1)) → (0, 0.5), (1, 1), (2, 1.5), etc.
  • closed dots at (x, ¹/₂x) → (1, 0.5), (2, 1), (3, 1.5), etc.

Each segment is joined with a horizontal line (step).
