If the derivative of function f (x) is f '(x) and f (x) = 3x2 + 2x * f' (2), then f '(5) =? Why isn't f'x = 6 + 2 * f'x when FX is derived?

If the derivative of function f (x) is f '(x) and f (x) = 3x2 + 2x * f' (2), then f '(5) =? Why isn't f'x = 6 + 2 * f'x when FX is derived?

If y = f (x) is derived, f '(x) = 6x + 2F' (x). If x = 2 is taken into account, f '(2) = 12 + 2F' (2), f '(2) = - 12. Then f' (5) = 30-24 = 6
Note that in the title, f '(2) is a fixed value
Two numbers that become coprime numbers () A. only common divisor 1 B. are prime numbers c. a prime number, a composite number
There are 10 bus stops on the bus line from the terminal to the station. A bus runs from the starting station to the terminal station. There are 9 passengers coming up at the starting station, 1 passenger coming down at the next station and 8 passengers coming up. After that, the number of passengers going down at each station is 1 more than that at the previous station, and the number of passengers coming up is 1 less than that at the previous station

How to find the derivative of F (x) = ln (2x + 3)?
f(x)=ln(2x+3)
Derivative: F (x) ′ = 2 / (2x + 3)
First of all, we should seek the derivative from the outside, then from the inside
f‘(x)=1/(2x+3)*2=2/(2x+3)
=2/(2x+3)
f(x)=ln(2x+3)
According to y = f [g (x)], y '= f' [g (x)] & ᦇ 8226; G '(x)
Let 2x + 3 = g (x)
ln(2x+3)=f[g(x)]
Then f '(x) = 1 / (2x + 3) * 2 = 2 / (2x + 3)
In the derivation of 2 / (2x + 3) composite function, we first take 2x + 3 as a whole and then multiply it by the derivative of 2x + 3

F (x) = x / (2x + 1)
solution
f(x)=x/(2x+1)
f'(x)=[x/(2x+1)]'
=[(x)'(2x+1)-x(2x+1)']/(2x+1)²
=(2x+1-2x)/(2x+1)²
=1/(2x+1)²
What are the meanings of factors, multiples, prime numbers and composite numbers
Factor and multiple: if the product of natural number a and natural number B is C, that is, a * b = C, then a and B are all factors of C, and C is the multiple of a and B
Prime: if a number has only one and two factors, such a number is called prime. Prime is also called prime
Composite number: a number with other factors besides 1 and itself. Such a number is called composite number
