Question

The absolute value function is one-to-one, while the greatest integer function is many-to-one.

A.True
B.False

Answer 1

Option B that is false.

Explanation:

The above statement is false because

Absolute value function is not one-one

For example:

|x|=x and |-x|=x

We are getting one vale at two different points.

And greatest integer function is many to one that is correct because

it will consider only the integer part

for example:

[1.05]=1 ,[1.02]=1 ,[1.06]=1 ,[1.08]=1

Hence, many to one

Nut one if false one is true

Hence, entirely it would be a false statement

Answer 2

The absolute value function is one-to-one, while the greatest integer function is many-to-one.

Answer: The statement shown above is false. The absolute value function is not not one to one, and the greatest integer function is not many to one. Therefore the correct answer choice is B) False. The best way to find whether a function is one to one is explained in the attachment.

I hope it helps, Regards.
