................-7..........

Answer:

Option A is correct.

-7

Step-by-step explanation:

Greatest function:

It indicates an integral part of the real number which is smaller and nearest integer to.

For example:

[tex][99.999] =99[/tex]

[tex][5.27] = 5[/tex]

As per the statement:

If [tex]g(x) =2[x]-1[/tex]

To find g(-2.3)

put x = -2.3

then;

[tex]g(-2.3) =2[-2.3]-1[/tex]

⇒[tex]g(-2.3) =2(-3)-1[/tex]

⇒[tex]g(-2.3)=-6-1= -7[/tex]

Therefore, the value of g(-2.3) is, -7
