The graph below represents the solution set of which inequality? -5 -4 -3 -2 -1 0 1 2 3 4 5
O x2 - 2x -8<0
O x2 + 2x -8<0
O X2 - 2x - 8>0
O x2 + 2x - 8>0

x2 + 2x -8<0

Step-by-step explanation:

Now we have the inequality; x2 + 2x -8<0. We have to solve it accordingly;

x^2 +4x-2x-8<0

x(x+4) -2(x+4) <0

(x+4) (x-2) <0

Hence the solution is (-4,2).

What we have now obtained is the same as the region required for the inequality hence this must be the correct option that we need to find in this question.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
