multiple choice question plz help

Respuesta :

Step-by-step explanation:

Considering the function

[tex]g\left(x\right)=x[/tex]

Checking the statement A)

As

[tex]g\left(x\right)=x[/tex]

Putting x = -5.7 in the function

[tex]g\left(-5.7\right)=-5.7[/tex]

Rounded to the nearest 1 or  the Ones Place.

[tex]g\left(-5.7\right)=-6[/tex]

But, original statement is [tex]g\left(-5.7\right)=-5[/tex].

So, the original statement is NOT TRUE.

Checking the statement B)

As

[tex]g\left(x\right)=x[/tex]

Putting x = -2.3 in the function

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

Rounded to the nearest 1 or  the Ones Place.

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

As original statement is also  [tex]g(-2.3)=-2[/tex].

So, the original statement is TRUE.

Checking the statement C)

As

[tex]g\left(x\right)=x[/tex]

Putting x = -0.6 in the function

[tex]g(-0.6) = -0.6[/tex]

Rounded to the nearest 1 or  the Ones Place.

[tex]g(-0.6) = -1[/tex]

As original statement is also [tex]g(-0.6) = -1[/tex]  .

So, the original statement is TRUE.

Checking the statement D)

As

[tex]g\left(x\right)=x[/tex]

Putting x = 4.1 in the function

[tex]g\left(4.1\right)=4.1[/tex]

Rounded to the nearest 1 or  the Ones Place.

[tex]g\left(4.1\right)=4[/tex]

But, original statement is [tex]g\left(4.1\right)=5[/tex].

So, the original statement is NOT TRUE.

Checking the statement E)

As

[tex]g\left(x\right)=x[/tex]

Putting x = 7.5 in the function

[tex]g\left(7.5\right)=7.5[/tex]

Rounded to the nearest 1 or  the Ones Place.

[tex]g\left(7.5\right)=8[/tex]

But, original statement is [tex]g\left(7.5\right)=7[/tex]

So, the original statement is NOT TRUE.
