The answer to the question is d
Answer: 0
Step-by-step explanation:
Since the line is horizontal and the y-values don't change, the slope is 0. The slope represents the change in y-values, but since the y-values are the same for all x values, there is no change and the slope is 0.
You can check this by picking two points and finding the slope through (y2-y1)/(x2-x1)
if we use the points (3,5) and (4,5) we get that the slope is (5-5)/(4-3) = 0/1 = 0
The range of a function is the set of possible values that can be obtained from the dependent variable. The range of the function is: 
Given that:


Let the number of months be t. So, the function C(t) is calculated as follows:



The range is calculated as follows:
The smallest possible value of t is 0 i.e. when no monthly subscription is done.
So, we have:

And the highest is
i.e. for a large value of t
So, we have:

Hence, the range of the function is:

Hi!
it is Allah's punishment when you do evil. when you die, you will tell him because of his sins before God.
