Use the universal set U= {a,b,c,….. y, z} and the characteristic function for the specified subset to compute the following function value:
[2.78] NOTE: Please ignore the “bracket” as it is the closest I could find to notation for a ceiling function. This could be simpler then I am making it and I think all I have to do is utilize the ceiling function. c(2.78)=3 but the first part of the question throws me off.
a. 3
b. -3
