Answer 1

Answer:

2    $\Rightarrow$     7

-2   $\Rightarrow$    -1

3     $\Rightarrow$     14

-3    $\Rightarrow$     2

Step-by-step explanation:

$f(x) = x^{2} + 2x -1$

$f(2) = 4 + 4 -1 = 7$

$f(-2) = 4 - 4 -1 = -1$

$f(3) = 9 + 6 -1 = 14$

$f(-3) = 9 - 6 -1 = 2$

Therefore

2    $\Rightarrow$     7

-2   $\Rightarrow$    -1

3     $\Rightarrow$     14

-3    $\Rightarrow$     2
