Answer:
2 [tex]\Rightarrow[/tex] 7
-2 [tex]\Rightarrow[/tex] -1
3 [tex]\Rightarrow[/tex] 14
-3 [tex]\Rightarrow[/tex] 2
Step-by-step explanation:
[tex]f(x) = x^{2} + 2x -1[/tex]
[tex]f(2) = 4 + 4 -1 = 7[/tex]
[tex]f(-2) = 4 - 4 -1 = -1[/tex]
[tex]f(3) = 9 + 6 -1 = 14[/tex]
[tex]f(-3) = 9 - 6 -1 = 2[/tex]
Therefore
2 [tex]\Rightarrow[/tex] 7
-2 [tex]\Rightarrow[/tex] -1
3 [tex]\Rightarrow[/tex] 14
-3 [tex]\Rightarrow[/tex] 2
