Q2 (2) Find the domain and range of the following real functions:
Given function is
Domain: These are the values of x for which f(x) is defined.
for the given f(x) we can say that, f(x) should be real and for that,9 - x2 ≥ 0 [Since a value less than 0 will give an imaginary value]
The domain of f(x) is
If we put the value of x from we will observe that the value of function varies from 0 to 3
Range of f(x) is
