Question

how do you find the domain and the range of f(x)=sqrt(x)?

Answer 1

We only Deal with Real Valued Function....if x is negative then the function is Undefined

So Domain = x>=0 Domain = [0 , infinity)

Answer 2

domain will b any positive real number

Answer 3

Range = [0,infinity)

Answer 4

range will b any positive real number

Answer 5

ok, so the domain and range in this case are basically the same thing because only x is given under the radical and the only thing we can't have is negative numbers?

Answer 6

ya x will not b any negative number

Answer 7

thanks

Answer 8

if x is negative then\[\sqrt{x}\] will b complex number
