Answer:

Option A) (-3,0)

Explanation:

We are given an inequality:


y> [x] + 3

Here [x] is the greatest integer function and defined as:

  • ⌊x⌋=the largest integer that is less than or equal to x for all real values of x.

The attached image shows the graph for the given inequality.

A) (-3, 0)


y> [x] + 3\\0 > [-3] + 3\\0 > 0

which is not true.

B) (-3, 6)


y> [x] + 3\\6 > [-3] + 3\\6 > 0

which is true

C) (0, 4)


y> [x] + 3\\4 > [0] + 3\\4 > 3

Thus, (-3,0) is not a point in solution for given inequality.
