Question

Evaluate the input/output table for the expression 2x - 4.х- 1012

Answer 1

Let's evaluate every value:

`\begin{gathered} y=2x-4 \\ for \\ x=-1 \\ y=2(-1)-4=-2-4=-6 \\ ------------------- \\ for \\ x=0 \\ y=2(0)-4=0-4=-4 \\ -------------- \\ for \\ x=1 \\ y=2(1)-4=2-4=-2 \\ ----------- \\ for \\ x=2 \\ y=2(2)-4=4-4=0 \end{gathered}`
