Is the function y = 1/x, shown in the graph below, invertible? If not, what is the restriction on the domain that will change it from non-invertible to invertible? a.) No, the function is not invertible. If the domain is restricted to x>1 or x<-1, then it will become invertible.
b.) No, the function is not invertible. If the domain is restricted to -1≤x≤1, then it will become invertible.
c.) Yes, the function is invertible.
d.) No, the function is not invertible. If the domain is restricted to x>0 or x<0, then it will become invertible.
