What is the value of the function y=2x−3 when x=−1 ?

−5

−1

Try substituting/plugging in your x-value into the x variable in the equation to find out what y is. Usually, you'd solve for y when given x.
\(y=2(-1)-3\)
You just have to multiply your x-value by 2, and subtract 3 to result your y-value.

Y=2x-3

Y=2(-1)-3

Y=-2-3

Y=-5

So your answer is A. -5
