Graph the function y = √ x + 4 – 2. Then state the domain and range of the function.
2 answers:
Answer:
Domain : [-4, ∞)
Range : [ -2, ∞)
Step-by-step explanation:
The given function is y =
Domain of the given function will be
(x + 4) ≥ 0
[ Since square root of numbers less than 0 is not possible ]
Domain : x ≥ (-4)
Or [-4, ∞) will be the domain
Now range of the function will be x ≥ -2
[ -2, ∞) will be the range of the given function.

Answer:
=
+
+ C where C is the constant of integration.
Step-by-step explanation:
i)it is given that the rate of change of W with respect to x is proportional to
x + 18. Therefore = k(x + 18) where k is a constant.
ii) Therefore =
+
+ C where C is the constant of integration.
iii) the complete solution can only be found if we know the constant of proportion and also the constant of integration.
