Answer:
I don't know does it fold up or anything?
Step-by-step explanation:
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:
y = 4x + 12
Step-by-step explanation:
The slope of the line y = 4x - 9 is 4.
The slope of the line we are looking for is also 4.
y - y1 = m(x - x1)
y - 4 = 4[x - (-2)]
y - 4 = 4(x + 2)
y - 4 = 4x + 8
y = 4x + 12
Answer: y = 4x + 12
Because this equation is in slope-intercept form, we can tell exactly how it will look by checking out 3 key points.
Leading coefficient: negative, or positive.
In this case, the leading coefficient is positive, which means that the slope will be going from bottom left to upper right.
Leading coefficient = slope
In this case, the slope is 4, or 4/1, so it will be at a steep incline.
Value of constant = y-intercept.
In this case, the y-intercept is -2, which will help us narrow down our choice.
<h3><u>After reviewing the three answer choices, the most likely selection will be A, as it seems to have a slope of 4, it is positive, and it has a y-intercept of -2.</u></h3>
