Question

how do i find the domain and range for f(x) = (sqrt) (x^2-3x)

Answer 1

\[f(x)=\sqrt{x^2-3}?\]

Answer 2

Look at where you'll get 0 or undefined for domain.

Answer 3

\[f(x) = \sqrt{x ^{2}-3x}\] this is the equation given. find the domain and range

Answer 4

Try plotting the real part of it, you should get a good idea of what it is from there:
