Answer:


Step-by-step explanation:
Given [Missing from the question]
Equation:

Interval:


Required
Determine the values of 
The given expression:

... shows that the value of
is positive
The cosine of an angle has positive values in the first and the fourth quadrants.
So, we have:

Take arccos of both sides

--- In the first quadrant
In the fourth quadrant, the value is:


So, the values of
in degrees are:

Convert to radians (Multiply both angles by
)
So, we have:




The domain is all ur x values...the range is all ur y (or f(x) values
so ur domain is : { -6,-1,0,3}....1st answer choice
Answer:
-12h^2-4+9-3h^2
Final result :
-5 • (3h^2 - 1)
Hope This Helps! Have A Nice Day!!
