Best ResponseYou've already chosen the best response.1this function here, that you posted is a polynomial

Best ResponseYou've already chosen the best response.1that function includes any xvalue in it's domain. It is continuous over \((\infty,~+\infty)\)

Best ResponseYou've already chosen the best response.1there are no excluded x values in a polynomial.

Best ResponseYou've already chosen the best response.0Are you sure because I have already tried answering this and I put 0, and it says that i'm wrong. The options are: 0, 1, 2, and 3.

Best ResponseYou've already chosen the best response.1you put y=4x1, you see that, correct?

Best ResponseYou've already chosen the best response.1maybe it is \(\large\color{black}{ \displaystyle y=\frac{\rm something}{\rm another~~something } }\)

Best ResponseYou've already chosen the best response.1oh, \(\large\color{black}{ \displaystyle y=\frac{4}{x1} }\)

Best ResponseYou've already chosen the best response.1what number can't you divide by, do you know?

Best ResponseYou've already chosen the best response.14 ÷ what = undefined or indeterminate ?

Best ResponseYou've already chosen the best response.1you can divide by 1, you can divide by 3, you can divide by 0.0003, but you can NOT divide by 0. right?

Best ResponseYou've already chosen the best response.1you can divide by anything, but not by 0

Best ResponseYou've already chosen the best response.1so, in your function \(\large\color{black}{ \displaystyle y=\frac{4}{x1} }\) , there is one xvalue that will not give you an adequate output, because you would need to divide by 0.

Best ResponseYou've already chosen the best response.1you are dividing by x1. so, when (for what xvalue) is this the same as dividing by 0 ?

Best ResponseYou've already chosen the best response.1(in other words, when "x1" is equivalent to 0? when x=what ?)

Best ResponseYou've already chosen the best response.1ok, lets go about it in a different way...

Best ResponseYou've already chosen the best response.1you can't divde by 0, you know that?

Best ResponseYou've already chosen the best response.1in our case we are dividing 4 by "x1", yes?

SolomonZelman

Best ResponseYou've already chosen the best response.1now, when dividing by x1, is going to be the same thing as dividing by 0, that will give us an undefined result.

SolomonZelman

Best ResponseYou've already chosen the best response.1dividing by x1 is same as dividing by 0, when x1 is same as 0. there is one xvalue for which x1 is same as 0. x1=0 when is x1=0?

Best ResponseYou've already chosen the best response.1I tried my best, I apologize, but I don't think I can help you more. I am capable of you the answer, but I am not going to.

Best ResponseYou've already chosen the best response.0@SolomonZelman I think I am understanding this more. x1=0 is 11=0 is this correct?

Best ResponseYou've already chosen the best response.0So this would mean that the excluded value is 1 right? @SolomonZelman

Best ResponseYou've already chosen the best response.1yes, yes very good!

Best ResponseYou've already chosen the best response.1the excluded value is 1. x≠1
