C. 2

D. 6

Answer 1

The answer to your question is ..

B || -4

Answer 2

Option B.

Explanation:

The given function is

`y=3x-1`

We need to find the value of the function when x=-1.

Substitute x=-1 in the given function.

`y=3(-1)-1`

On simplification we get

`y=-3-1`

`y=-4`

The value of the function y=3x−1 is -4 at x=−1.

Therefore, the correct option is B.
