attachment 1
Can a function be increasing and be concave down everywhere?
no, concave down means increase slope then decrease slope
Can a function have two local extrema and three inflection points?
inflection points are where the concavity changes
it can be at the ends, the middle and the other end
like in atachment 2, the circles are inflection points
Can a function have 4 zeros and two local extrema?
no, as you can see in attachment 3, there can be 3 zeroes at most for 2 local extrema

<em>Think of it as a riddle.</em>
You need to eliminate and match one city to one transport to one person in the end.

Take a look at my diagram!*
Use each clue to eliminate the rows and columns until you have narrowed it down.
Below is my work. It would be too hard to explain every step of the way; it will work differently for everyone. Maybe look up the game "Telepathy". The concept is similar!
-----------------------------------------------------------------------------------------------
<em>I first read the instructions, eliminating and boxing the possible and impossible options. </em>
<em>If I ever got down to one empty spot in a column or row, I'd make sure to circle that and frequently write it down.</em>
<em>If you're doing this right, you will </em><em>always be progressing</em><em>. </em><u><em>Don't doubt yourself; don't overthink it</em></u><em>. It's the game of </em><em>narrowing down and elimination</em><em>. If you find yourself stuck, </em><u><em>write what you know down.</em></u><em> </em><em>Use logic</em><em>. Make sure you </em><u><em>always</em></u><em> look for rows that you forgot to cross out, or empty spots that you missed. </em><em>Reread</em><em> the instructions! </em><u><em>You will get there</em></u><em>! </em>
-----------------------------------------------------------------------------------------------
*The "eliminated" part is a bit confusing, they weren't entirely eliminated. It's just my thought process! I didn't continue to use it. Just remember to group the right things together!
Don't be scared of looking up the cities and if you don't know, their states!
