y = -4

 B.) -4 is your answer

Answer:

Option B is correct

Value of the function [tex]y =3x-1[/tex] when x =-1 is -4

Step-by-step explanation:

Given the function: [tex]y =3x-1[/tex]          ......[1]

Here, x is the input value and y is the output value.

Substitute the input value of x = -1 in [1]

[tex]y =3(-1)-1[/tex]  

⇒[tex]y =-3-1[/tex]  

⇒[tex]y =-4[/tex]  

Therefore, the value of the function [tex]y =3x-1[/tex] when x = -1 is -4
