Answer:
Domain : −4≤x≤4, in interval notation : [−4,4]
Range: 0≤f(x)≤4, in interval notation : [0,4]
Explanation:
f(x)=√16−x2 , for domain under root should not be
negative quantity. 16−x2≥0or16≥x2orx2≤16
∴x≤4orx≥−4 . Domain : −4≤x≤4or[−4,4]
Range : f(x) is maximum at x=0,f(x)=4 and
f(x) is minimum at x=4,f(x)=0
Range : 0≤f(x)≤4or[0,4]
Domain : −4≤x≤4, in interval notation : [−4,4]
Range: 0≤f(x)≤4, in interval notation : [0,4]
