Answer 1

$- 2x + 3$

$x = - 3 \\ - 2 \times ( - 3) + 3 = 6 + 3 = 9$

$x = - 2 \\ - 2 \times ( - 2) + 3 = 4 + 3 = 7$

$x = - 1 \\ - 2 \times (- 1) + 3 = 2 + 3 = 5$

$x = 0 \\ - 2 \times 0 + 3 = 0 + 3 = 3$

$x = 1 \\ - 2 \times 1 + 3 = - 2 + 3 = 1$

$x = 2 \\ - 2 \times 2 + 3 = - 4 + 3 = - 1$

$x = 3 \\ - 2 \times 3 + 3 = - 6 + 3 = - 3$
