Answer
Pairs: $(-3,14),\ (-2,5),\ (-1,0),\ (0, -1),\ (1,2),\ (2, 9),\ (3, 20)$
Range: $\{-1,0,2,5,9,14,20\}$
Graph:
Work Step by Step
$y=(2x-1)(x+1)=2x^{2}+x-1$
$\left[\begin{array}{rrrrrrrr}
x: & -3 & -2 & -1 & 0 & 1 & 2 & 3\\
y: & 14 & 5 & 0 & -1 & 2 & 9 & 20
\end{array}\right]$
Pairs: $(-3,14),\ (-2,5),\ (-1,0),\ (0, -1),\ (1,2),\ (2, 9),\ (3, 20)$
Range: $\{-1,0,2,5,9,14,20\}$
