because there is only one value where that fraction is undefined
and it will be defined for all other values of x
undefined. sorry AGAIN!! haha XD
so it'll be undefined when the denominator equals 0 ! :)
when is x-7 =0 ??
for what value of x ?
so just 7. haha
\(\huge \checkmark \)
but what does undefined mean and how does that make a role in the question
what is the value of say 1/0 ??
or can any number be divided by 0 ?
we haven't defined what we get as a result of 'division by 0'.
hence in any expression,
when we get a denominator as = 0 , we say its undefined..
in your question the denominator was x-7
OH. hahah got it;)
Darn it I missed the question... as for undefined numbers.... the reason division by zero is undefined is because you can fit an arbitrary number of 0s into a number. Infinite if you like, and still not get close to it. So dividing by zero outputs a set... which is another kind of construct all together... :O
