We have some number x that we do two things to it in this exact order: divide by 3, add 8.
To isolate x or get it all by itself, we have to undo what is happening to x. We follow the order mentioned above in reverse so that we undo everything properly. Undo the "add 8" by subtracting 8 from both sides. Then you undo the "divide by 3" by multiplying both sides by 3. Check out the attached image for details and the steps on how to solve. The final answer is x = 18

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.
