Enter the table of values used for this plot

Help, please, with the task.

If x = -0.6, then y = -2.777... and ad infinitum. At what point do I start to decide wrong, can you please tell me also? I'm stuck at this point and can't continue. Thank you

x = [-5:-1 -0.8:0.2:-0.2];
x = [x -x(end:-1:1)]

x = 1×18

-5.0000 -4.0000 -3.0000 -2.0000 -1.0000 -0.8000 -0.6000 -0.4000 -0.2000 0.2000 0.4000 0.6000 0.8000 1.0000 2.0000 3.0000 4.0000 5.0000

y = 1./x.^2

y = 1×18

0.0400 0.0625 0.1111 0.2500 1.0000 1.5625 2.7778 6.2500 25.0000 25.0000 6.2500 2.7778 1.5625 1.0000 0.2500 0.1111 0.0625 0.0400

result = reshape([x; y],1,[])

result = 1×36

-5.0000 0.0400 -4.0000 0.0625 -3.0000 0.1111 -2.0000 0.2500 -1.0000 1.0000 -0.8000 1.5625 -0.6000 2.7778 -0.4000 6.2500 -0.2000 25.0000 0.2000 25.0000 0.4000 6.2500 0.6000 2.7778 0.8000 1.5625 1.0000 1.0000 2.0000 0.2500
