Question

What is the value of the function y=3x−1 when x=−1 ?

Answer 1

Answer:

Option B.

Step-by-step 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.

Answer 2

Y- -4 because


y=3(-1)-1

y=-3-1
(because 3*-1=-3

y=-4
(because -3-1=-4)
