## anonymous one year ago how do you find the domain of the function: u (x)= square root of -6x+12

$$u(x) = \sqrt{-6x + 12}$$ We know that the only restriction on the function is that: $$-6x+12 \ge 0$$ Because for all real $$\sqrt{a} \implies a \ge 0$$ Now, solve the inequality and you'll get the restrictions on the domain.
