A={a, b,c}, B={9,16,25}, and f={(a,9),(b,16),(a,25)}. True or false, f is a function from A to B?

Explanation:

The input x = a leads to multiple outputs y = 9 and y = 25 at the same time. This is due to the points (a,9) and (a,25) in the set f.

A function can only be possible when any x input leads to exactly one y output only. You'd need to get rid of either (a,9) or (a,25) to make this a function.

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
