CPM Homework Help : CCA2 Problem 1-92

Create multiple representations ( $x→y$ table, graph, and equation) of the function $g(x)=\frac{2}{x}$ . Then make at least 3 summary statements.

Hint:

What happens to the value of $y$ when you let $x=0$ in the equation? Use that information to help you describe the domain. Where do you see this on the graph? How does it appear in the table? Describe.

More Help 1:

Is there any number that cannot be an output? Think about this in terms of the equation. Use that information to help you describe the range. How do you see this on the graph? How does it appear in the table? Describe.

More Help 2:

Does this graph have $x$ - or $y$ -intercepts? Why? Discuss this in terms of the equation, the graph, and the table.

More Help 3:

What can you say about symmetry? Do you see it in the table? On the graph? In the equation?

More Help 4:

Make sure to justify your summary statements using multiple representations.

x	y
$-3$	$-\frac{2}{3}$
$-2$	$-1$
$-1$	$-2$
$-0.5$	$-4$
$0$	undefined
$0.5$	$4$
$1$	$2$
$2$	$1$
$3$	$\frac{2}{3}$
