Which of the following graphs represents the function f(x) = x4 - 2x3 - 3x2 + 4x + 1?
s2008m [1.1K]

Answer: Graph D will be correct graph for the given function.

Explanation:

Given function f(x) = x^4-2x^3-3x^2+4x+1

Since it is a bi-quadratic equation thus it must have 4 roots and (0,1) is one of its point.

Moreover, the degree of the function is even thus the end behavior of the function isf(x)\to+\infty, as x\to-\infty and f(x)\to+\infty as x\to+\infty

In graph A, function has four root but it does not have the end behavior same as function f(x).( because in this graph f(x)\to-\infty, as x\to-\infty and f(x)\to-\infty, as x\to+\infty.) so, it can not be the graph of given function.

In graph B,  neither  it has four root nor it has the end behavior same as function f(x).(because in this graph f(x)\to+\infty as  x\to-\infty and f(x)\to-\infty as x\to+\infty.) so, it can not be the graph of given function.

In graph C, neither  it has four root nor it has the same end behavior as function f(x).(because in this graph f(x)\to-\infty as  x\to-\infty and f(x)\to+\infty asx\to\infty.) so, it also can not be the graph of given function.

In graph D it has four root as well as it has the same end behavior as the given function. Also it passes through the point (0,1).

Thus, graph D is the graph of given function.

A long year-end status report for work is 130 pages long. You need to print 17 copies for a meeting next week. How much is the p
Nikitich [7]
The first thing you should do in this case is to know how much paper you need to print for the 17 copies.
 We have then:
 (17) * (130) = 2210
 Then, you must calculate the number of reams you need:
 n = (2210) / (500) = 4.42
 You need 4 full reams and 42% of a fifth ream. So, the cost will be
 C = (4.42) * (3.44) = 15.2048 $
 The unit cost of each paper is:
 Cu = (15.2048) / (2210) = 0.00688 $
 answer
 the paper is going to cost 0.00688 $ for those reports

if I went to store with 90.00 and spent 36.81 and got 20% off what would I have left need answer fast thanks
vichka [17]
I'm guessing the 20 percent off is from the $36.81 so you take 36.81 times 0.80 making it $29.448. Take 90 dollars and minus that amount.

Answer: $60.552 
Rounded Answer: $60.55 or $60.60 or $61

Not sure if this helped, but yeah.....
