Another function problem (funny symbols like this are nothing but disguised functions). As you should with any function problem, remember to take this ONE STEP AT A TIME, to RE-WRITE THE DEFINITION OF THE FUNCTION and to STACK THE ACTUAL VALUES UNDERNEATH ON THE LEFT SIDE OF THE EQUATION, following the model on the right side.
The goal of any “funny symbol problem” is to get rid of the funny symbols, ONE AT A TIME, so don’t set “1 arrow 2” equal to “2 arrow x” until you’ve removed the arrows from both expressions.
If you try to do this all at once you will surely get it wrong…remember, you know that it’s a hard problem (#17 out of 20), so take your time.
