Homework Statement
I had a question about intervals and their reciprocals. If you have the reciprocal I where I is [r,s] than the reciprocal is [1/s , 1/r]. My question is when an interval contains zero, does the interval have a reciprocal. For instance if J is the interval [-2,7] does J have a reciprocal, and if so what is the formula for finding it?
Homework Equations
I = [r,s]
1/I = [1/s , 1/r]
