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

a. −8

b. −4

c. 2

d. 6

Option B.

Step-by-step explanation:

The given function is

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

Substitute x=-1 in the given function.

On simplification we get

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

Therefore, the correct option is B.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
