Determine if f(x) = round(x) is a one to one function
This question is best answered using illustrating values;
Let x = 1.1
f(x) = round(x) becomes
f(1.1) = round(1.1)
f(1.1) = 1
Let x = 1.3
f(x) = round(x) becomes
f(1.3) = round(1.3)
f(1.3) = 1
Notice that for the two values of x, f(x) has the same value of 1.
This two illustrating values can be used to conclude that the fuction is not one-to-one.
