Question

find the domain and range of
$\sqrt{9 - {x}^{2} }$
​

Answer 1

Answer:domain{x:-3≤x≤3}

Range{x:0≤x≤3}

Step-by-step explanation:

Range cannot exceed 3 because the root cannot be negative and 0 is the last maximum value of this equation

Domain can only be -3 and 3 because root of the equation can only come between -3 and 3
