Question

use the domain {-4, -2, 0, 2, 4} the codomain [-4, -2, 0, 2, 4} and the range {0, 2, 4} to create a function that is niether one-to-one nor onto

Answer 1

Answer:

See attachment

Step-by-step explanation:

We want to create a function that is neither one-to-one or on to given that:

The domain is {-4, -2, 0, 2, 4}

The codomain is [-4, -2, 0, 2, 4}

The range is  {0, 2, 4}

The function in the attachment is an example of such function.

The function is not one-to-one because there are different different x-value in the domain that has the same y-value in the co-domain.

It is not an on to function because the range is not equal to the co-domain.
