Hello, thekrown!
Given: .
Find
The domain of is: .
The domain of is: .
. . Hence, the domain of is: .
Hence, ranges between: .
. . Therefore, the range of is: .
Okay so I have the function f(x) = square root of 9-x^2 and g(x) = square root x+3
I must find f of g
This is square root 9 - (square root x+3)^2
Now I must find the domain and range. Here is my attempt:
Simplified I have square root 6-x. Since x cannot be 6 or greater the domain must be (-infinity, 6). The range is (6, +infinity).
