What is the value of the function y=2x−3 when x=−1 ?
−5
−1
2
3

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.

You just have to multiply your x-value by 2, and subtract 3 to result your y-value.

It creates dogx^2 and then flip your answer and multiply by 2
