Hi,

what is the elements of the set below

B = {-2k/3 e Z, k e R | |k| < 9 }

My work is shown below

the range of |k| is [0,9[

the range of k is ]-9,9[

so put [-8.999... , 8.999...] into -2k/3 and I got the integers below

B = {-5,-4,-3,-2,-1,0,1,2,3,4,5}

Is my answer correct?

Thank you!

Jason
