Answer:
The given sequence is:
a(2)=1
a(3)=3
a(4)=9
We are to find the average rate of change between n=3 and n=4 for the given function.
Average rate of change =
So the average rate of change for the given function from n = 3 to n = 4 is 6

Answer: The fraction 2/5</h3>
=========================================================
Explanation:
We have three points marked on this diagonal line. Each point has integer or whole number coordinates. I find it is easiest to start with the y intercept, which in this case, is the point (0,0). This is the origin.
From the origin, move 2 units up and 5 units to the right to arrive at the next neighboring point (5,2).
This shows that,
slope = rise/run = 2/5
The rise indicates how much we have gone up or down. The run is the amount you move to the right. If the rise is negative, then you have gone downhill. By "downhill", I mean when the graph is read from left to right.
-------
Optionally you can use the slope formula
m = (y2-y1)/(x2-x1)
with any two points you want from the graph.
Answer:
A. 
Step-by-step explanation:
A rational-polynomic function is a function of the form:
(1)
There are three important remarks on this kind of function:
1) 
when function passes through the x-axis.
2) If 
, then the function 
has a vertical asymptote.
3) The horizontal asymptote is a linear function of the form 
.
In accordance with the graph, the function has two vertical asymptotes at 
and 
, numerator becomes zero for 
and horizontal asymptote is 
as grade of numerator is less than grade of denominator.
Hence, we conclude that rational function is <em>. </em>(Correct answer: A)
