for an expression or relation to be a function, it must not have any x-coordinate values repeated, let's check this one

Answer:
B
Step-by-step explanation:
because it says between 4 and 8 and doesn't have a negative so its positive
The correct answer is B: 2,4,5, 10
We know that 100 is not divisible by 3 because 100/3 is 33.33 repeating, which is an irrational number.
We also know that 100 is not divisible by 6 because 100/6 is 16.66 repeating which is also an irrational number.
100/2=50 (rational)
100/4=25 (rational)
100/5=20 (rational)
100/10=20 (rational)
