Respuesta :

the correct answer is the first graph.  (top left)

check a few values of x to see that:

x = 0 --> y = -3

x = 0.1 --> y =-1

x = 1 --> y = -1

x = 1.1 --> y=1

etc.

The other choices are easily excluded by the above checks.

The graph (B) represents the greatest integer function y = 2⌈x⌉ − 3 option (B) is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The greatest integer function:

y = 2⌈x⌉ − 3

As we know,

An integer-valued function in mathematics is one whose values are integers. In other terms, it is a function that gives each object in its domain an integer.

By plugging the x-values in the function we can get respective y values and by plotting the values in the coordinate plane we can get a graph of the function.

y = 2⌈2⌉ − 3

y = 1

y = 2⌈3⌉ − 3

y = 3

Thus, graph (B) represents the greatest integer function y = 2⌈x⌉ − 3 option (B) is correct.
