Quick math question, why's this false ...If f(x)=x^2 and g(x) =sq.root (x+3) then f(g(x)) is defined for all x

I am having difficulty understanding why, could someone please explain it to me?Quick math question, why's this false ...If f(x)=x^2 and g(x) =sq.root (x+3) then f(g(x)) is defined for all x
F(x)= x+3 is definied for all x





But f(g(x)) only is definied when g(x) is definied (by definition) --%26gt;


f(g(x))=x+3 only where x%26gt;=-3





Saludos.

In successive approximation the steps are well defined and apply to all horses-true/false

huh???In successive approximation the steps are well defined and apply to all horses-true/false
What steps? I'm LOST! Try rewording this question so it makes sense.





Thanks Shannon, I was lost there and couldn't figure out what poster was asking...Another HOWRSE question huh?





:::Crawls out of the lost and confused box:::In successive approximation the steps are well defined and apply to all horses-true/false
It would help if you wrote out the entire question from Howrse. You only put half of it. XD You aren't really going to get an answer because Howrse is supposed to be a learning game (aka get your own answers).
Is this from Horwse

-The combining form encephal/o is defined as brain. True or False?

encephalo- means brain. You are correct, the answer is True.

True or False: If a function is not defined at x=5, then the function is not continous at x=5.?

true or False: If a function is not defined at x=5, then the function is not continous at x=5.True or False: If a function is not defined at x=5, then the function is not continous at x=5.?
True.True or False: If a function is not defined at x=5, then the function is not continous at x=5.?
Yes, that's TRUE. The function is good and continuous for all real values of x Except ';5'; which is missing from f(x)'s domain.
If said function is not defined at x=5, then it is not continuous over any set including this line. for example, this function is not continuous over the real numbers. This is a removable discontinuity, and can be fixed by redefining the function for that point. So true

True or False?....The more defined your body is...the more ticklish you are?

Is this actually true.....?True or False?....The more defined your body is...the more ticklish you are?
you will need some scientific theory and process to determine this...other wise its a possible theoryTrue or False?....The more defined your body is...the more ticklish you are?
nope...just think about it. if someone is super duper fatty there is more skin and more tickle zone present!!!

Defining functions, true or false..?

Answer true of false to the following questions:





1. It is possible to uniquely define a quadratic function given 4 distinct points.





2. It is possible to uniquely define a constant function given 4 distinct points.





3. It is possible to uniquely define a quartic function given 4 distinct points.





4. It is possible to uniquely define a cubic function given 4 distinct points.





5. It is possible to uniquely define a quintic function given 4 distinct points.Defining functions, true or false..?
Y = AX^2 +BX +C; it takes 3 points to uniquely define a quadratic; 4 points to uniquely define a cubic; etc.





1. T


2. T


3. F


4. T


5. FDefining functions, true or false..?
3. It is possible to uniquely define a quartic function given 4 distinct points - True


Others are false.

Which law of logic is defined as ';if a conditional is true and its consequent is false, then its antcecedent?

which law of logic is defined as ';if a conditional is true and its consequent is false, then its antcecedent is false';





1) Law of Syllogism (Chain Rule)


2) Law of COnjunct6ion (Law of Conjunctive Addition)


3) Law of Disjunctive Addition


4) Law of Modus TollensWhich law of logic is defined as ';if a conditional is true and its consequent is false, then its antcecedent?
I'll write it logically.





1) A -%26gt; B


2) ~B


// ~A





The law of logic is modus tollens.





I'm not sure what #1 is, but I know what the others are.





2) Law of Conjunctive Addition goes as follows:





1. A


2. B


// A * B





Law of Disjunctive Addition.





1. A.


// A v B





(essentially, once you know that something is true, it follows that that something ORed with someone else, whether it is true or false, is true).
