The answer to the question is 12,400
Given that,

To find,
The domain of f(x).
Solution,
We have, 
To find domain,
The term under the square root must be positive or null as follows :

Adding 3 both sides

So, the domain is x-3>0
.
Log₄(y+2) = 3, transform it into exponent form:
(y+2) = 4³
y+2 = 64
y= 62
