Question

what is the excluded value? 3x(_over)/1-3x

Answer 1

\[\left(\begin{matrix}3x \\ 1-3x\end{matrix}\right)\]

Answer 2

x=1/3

Answer 3

x=1/3 would be exc;ided as ot wwould result in division by zero

Answer 4

1/3

Answer 5

\[\frac{3x}{1-3x}\] is only valid when the denominator (bottom) is not zero. So the excluded value is when 1 - 3x = 0.

Answer 6

check out the graph: http://bit.ly/kmZoIC You can see at x=1/3, it "blows up." It will approach negative infinity coming from one direction and positive infinity coming from the other. At exactly x=1/3, the function is undefined.

Answer 7

so its 1over3?

Answer 8

yes.

Answer 9

Nice graph, I bookmarked that page.
