Question

domain and range of this function
m(x)=x√−10

anonymous · Answer

well if we w take it that -10 is squared, this is not a function of real numbers. it's a function of complex numbers, and you have domain - C, and range C, that is fun, but i am sure it's not what you're looking for.

anonymous · Answer

so what's expression is it sqrt(x)*-10 instead?

anonymous · Answer

$$m(x)=\sqrt{x}-10$$

anonymous · Answer

so x>=0 simple

anonymous · Answer

you can't have a square root of a negative number

anonymous · Answer

and think about the smallest value this function can take?
it's obvious it will be able to take all values bigger than it.
so it's range will be from that value to +infinity

OK, so the -10 has no influence on the calculation of the square root. Just subtract afterwards.
If we want to be able to calculate the square root of a number x, that number cannot be negative. So there is you domain...
If you want to know the range of m(x), you first need to know the range of √x.
Which numbers can be the outcome of √x? As soon as you know that, then think what subtracting 10 does to it.
