I am trying to determine the domain, co-domain and range of the following function
A function assigns to each integer, the square of that integer multiplied on 4.
What I think it is, is: f: X→√ℤ*4
But I suspect that I have some of the symbols in the wrong place?
I previously posted a similar question:
A function assigns to each bit string, the number of zeroes in that bit string.
