Which are points on the graph of y = 1.5 + ⌈x⌉? check all that apply. a. (–4.5, –2.5) b. (–1.5, 0) c. (–0.8, 0.5) d. (1.3, 3.5) e. (4.5, 6) f. (7.9, 9.5)

Option A,D and F

Step-by-step explanation:

Given : Function

To find : Which are points lie on the graph of given function?

Solution :          

To determine the points lie on the graph,

First we graphed the given function

In the function, ⌈x⌉ means the ceiling of x, i.e. the smallest integer greater than or equal to x.

Refer the attached figure below.

Now, We mark all the points mention in question.

We note the point line on the ceiling x are A(-4.5, -2.5), D(1.3, 3.5) and F(7.9, 9.5).

Therefore, The required result is Option A,D and F.
