Which points lie on the graph of the function f(x) = ⌈x⌉ + 2? Check all that apply.

The ceiling function ⌈x⌉ gives the least integer greater than or equal to x. For x = −1.1, −0.9, and 2.2, the ceiling values are −1, 0, and 3; adding 2 gives 1, 2, and 5. Therefore, (−1.1, 1), (−0.9, 2), and (2.2, 5) lie on the graph. The other points do not match the function values.
