Question

. Find domain and range of real function f(x) = √9- x^2

​

Answer 1

Domain is[ -3,3] Range is [0,3]

Answer 2

Answer:

Step-by-step explanation:

√(9-x^2) , so the value present in the sq root of any number is always (+).

ex:√9=3, 9 is (+)

so to proceed,

9-x^2<=0

so,

x^2=9 so x=-3 or 3

domain is (x)=-3,3
