You are very welcome!The ceiling function

the ceiling function [ ceil(x) ] maps x to the least integer greater than or equal to x.

For example :

ceil(3.4) = 4

ceil(-4.4) = -4

We need to graph the function:

f(x) = ceil (x) on the interval [-4,4]

Let's give x some values:

For x=-4 , ceil(-4) = -4

For x=-3.5, ceil (-3.5) = -3

Any value of x between -4 and -3 will have a value of -3

For x=-2.9, ceil(-2.9)=-2

Any value of x between -3 and -2 will have a value of -2

For x=-1.5, ceil(-1.5) = -1

Any value of x between -2 and -1 will have a value of -1

For x=-0.3, ceil(-0.3) = 0

Any value of x between -1 and 0 will have a value of 0

For x=0.8, ceil(0.8) = 1

Any value of x between 0 and 1 will have a value of 1

For x=1.2, ceil(1.2) = 2

Any value of x between 1 and 2 will have a value of 2

The graph will be shown right below
