do u see any values that 'x' can't take ?

(1)there is no denominator, if there was, then 'x' could not take values for which denominator=0

so ther is no soln for this??

(2) there is no \(\sqrt.\) sign, if there was , then 'x' cannot take values for which the expression under \(\sqrt{...}\)becomes negative.

hartnnBest ResponseYou've already chosen the best response.2
here, none of the 2 cases (1) or (2) arise. so 'x' can take all real values.

yes, x can take any real value. u have options/choices ?

how wud u solve this prob?
 one year ago

hartnnBest ResponseYou've already chosen the best response.2
example : f(x) =1/ x x cannot take value =0 f(x) = 1/(x3) x cannot take value = 3 f(x) = sqrt{x4} x cannot take value less than 4

can u be mo` specific...?i cant understand
 one year ago

hartnnBest ResponseYou've already chosen the best response.2
i just gave u specific examples. and there's nothing to solve, you can say 'x' can take all real values...

y did u add 3 in da denominator?

By the way, all polynomials have the domain \((\infty,\infty)\) a.k.a \(\mathbb{R}\).

can u do the whole process??

Domain means whenever the function exists. To figure this out, just find when the function does not exist, meaning when you're dividing by 0. In this case, you're never dividing by 0, so the function ALWAYS exists, so the domain is ]inf,inf[, also know as "R" for all real numbers. If say f(x) = 1/(x4), then the domain is ]inf,4[U]4,inf[, because the function exists everywhere except at x=4.
