Answer:

Option B is correct

Value of the function y =3x-1 when x =-1 is -4

Step-by-step explanation:

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

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

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

y =3(-1)-1  

⇒y =-3-1  

⇒y =-4  

Therefore, the value of the function y =3x-1 when x = -1 is -4
