The first two are the question being asked. Thats the work that I have done so far, but I am confused as to what I should do becuase there is no x value given.
Duplicate question. You should merge it with your earlier questions on the same topic.
I deleted the previous question because it seemed like the information provided was not clear enough.

Establish a vector of definite x values. Use logical indexing
X = something definite
Y = nan(size(x));
Mask = x > something & x < something else
Y(Mask) = some vectorized expression in X(Mask)
