The difference between the set of non-negative real numbers and the set of positive real numbers is: A. an infinite set B. a null set C. a singleton set D. Null set

C; A singleton set

Step-by-step explanation:

Mathematically, when a number is non-negative; it is either positive or zero

Now, this is because 0 identifies as neither a positive or a negative number

hence, when we find the difference between the two sets, the only number that stands out unmatched is the value 0

What this mean is that we are having a set with a single number result

So we have our answer as {0}

Which is a singleton set

f(x) = y

f(-3) = -5
