Hi Nathan02079!

Are you supposed to be solving the inequality for x? Or just evaluating the function until you find what is ? - January 30th 2009, 07:34 PMnathan02079
I am solving for x.

Looks good to me!

**NOT**yet

First of all you need to find the values of x for which all the square roots are possible.i.e quantities under the square root signs must be non-negative.

On taking the intersection of the above conditions you will get

which can be said to be the domain of the inequality.

Now the solutions you obtain by solving

i.e

i.e

Therefore the values of x satisfying both the inequalities are

which must satisfy .

Therefore the answer to the given question must be [5,7] - February 1st 2009, 09:06 AMvg284
i think answer is [4 7].

Take and put it in ,you will obtain which is impossible since is not possible in real numbers

Therefore the answer to the given question must be {4}u[5,7]

That's correct.
