Question

Over which interval of the domain is function h decreasing? A. B. C. The function is increasing only. D.

Answer 1

Answer:

As this question is incomplete and lacks equation of functions to be dealt with. So, I am generally explaining the answer to this question.

1. If derivative of that function gives you a position value, it means it is increasing function.

2. If derivative of that function gives you a negative value, it means it is decreasing function.

Step-by-step explanation:

If you have equations of functions then following is the way to determine whether that function is increasing or decreasing.

Process: If you want to know a particular function is increasing or decreasing then simply you have to take derivative of that function:

If derivative of that function gives you a position value, it means it is increasing function. $f^{'} (x) >0$ increasing

If derivative of that function gives you a negative value, it means it is decreasing function. $f^{'} (x)$ decreasing
