8. Functions, Domain and Range

Read this carefully: Do the following questions under timed conditions.

You may not be able to answer any of the questions, that's totally fine. These exam questions are really difficult and most students struggle with them.

Once you've finished, look at the answers and then mark yourself. After that, work out how to do the questions that you couldn't answer.

Now complete these questions again (under timed conditions and without looking at the answers). Then mark yourself again. Keep doing the questions over and over until you feel happy with the mark you got.
