What is the image of the derivative of F (x) = (x-1) (X-2) (x-3) (x-4)


The function f (x) = (x-1) (X-2) (x-3) (x-4) is obviously a fourth power function. Its domain of definition is any real number. The function is continuous and differentiable everywhere during the whole real number period. It is easy to find that the equation f (x) = 0 has only four solutions, that is, the image of the function intersects the X axis four times, and the intersection points are x = 1,2



It is known that the derivative f (x) is the derivative of the function y = f (x), and the image of y = derivative f (x) is shown in the figure, then the derivative of y = f (x) is the derivative of the function y = f (x)

How to find the derivative of y = (x + LNX) / (x + Ex)?


Is ex a multiplication of E and X? Or an exponential function? I did it as a multiplication. Y '= [(1 + 1 / x) (x + Ex) - (x + LNX) (1 + e)] / (x + Ex) & # 178; = (E + 1) (1-lnx) / [(1-lnx) / [(E + 1) x & # 178;] hope it can help you.

What's the difference between simple sentences and complex sentences?
He collected pieces of dried moss and boiled water to drink
2. With his will to survive, he still struggles to crawl
Due to long-term overwork, Mr. Li finally fell ill and was hospitalized
4. If the U.S. government still insists on confrontation, the Chinese government is willing to accompany it to the end
Which of the four sentences are complex, which is single, and why?


Look at the whole sentence, there is a set of subject, predicate, object is a single sentence, that is, a simple sentence. And there are multiple is a complex sentence. According to this principle, 1,2,3 is a single sentence, 4 is a complex sentence



The essential difference between complex sentences and simple sentences lies in () and ()
