Find the range of f(x) = root (9-x2) Share with your friends Share 7 Manbar Singh answered this We have, fx=9-x2Clearly fx is not defined when 9-x2<0, that means fx is definedonly when 9-x2≥0.Now, 9-x2≥0⇔x2-9≤0⇔x2≤9⇔x≤3 or x≥-3⇔-3≤x≤3⇔x∈-3,3Now, for each x∈-3,3, fx=9-x2 will have a value in the interval 0,3.So, range f = 0,3 24 View Full Answer
