Let’s think about the graph of the equation y=2/x. 1. make a table of (x, y) pairs that will help you graph the equation. make sure to include some negative number for x and some numbers that are not integers.

2. plot the graph on the coordinates axes. you may need to find a few more points to plot to make the graph look smooth.

3. The coordinate plane provided is too small to show the whole graph. what do you think the graph looks like when x is between 0 and 1/2? try some values of x to test your idea.

4. what is the largest value that y can ever be?

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?

first 15 divide by 2 = 7.5

100 divided by 7.5 is 13.

15 / 2 = 7.5

100 / 7.5 = 13.
