Find the value of $y=3x-1$ when $x=-1$ .

STEP 1

Assumptions1. We are given the function $y=3x-1$ . We are asked to find the value of the function when $x=-1$

STEP 2

To find the value of the function, we need to substitute $x=-1$ into the function.
$y =(-1) -1$

STEP 3

Perform the multiplication operation first according to the order of operations (PEMDAS/BODMAS).
$y = -3 -1$

STEP 4

Now, perform the subtraction operation.
$y = -4$ So, the value of the function $y=3x-1$ when $x=-1$ is $-4$ .
