There is a formule: S = 1/2 n (n + 1)
Here is n = 100

4(x-2)/(x-3) + 3/x = -3/x(x-3)
4x(x-2)/x(x-3) + 3(x-3)/x(x-3) = -3/x(x-3)
x cannot be 0 or 3
4x^2 - 8x + 3x - 9 = -3
4x^2 -5x -6 = 0
(x-2)(4x+3) = 0
x = 2 or x = - 3/4

If it had been 16392=x^2, you would have taken the
square
root of it. Now that it's cubed, you have to take the
cube
root, which would result in 25.403.

Differentiate the equation of the curve and equate it to -3, get the value of x from equating the dy/dx equation to -3 and substitute the value of x with the original equation to get the corresponding value of y. Then for the second question you substitute the value of the x and y into the equation y2-y1/x2- x1 where the values of x and y are the values gotten from the first solution and equate it to -3 and make it in the form of y= mx+c and that is the equation of the tangent

$175 - 20%
$175*0,2 = $35. $35 = 20%
$175 - 20% = $140

4x^3-4x^2-15x+18=0
potential rational zeros: 1,2,3,6,9,1/2, 1/4,3/2,3/4
f(x)= 4x^3-4x^2-15x+18
f(1)= 4-4-15+18
is not = 0
so u substitute f(x) with a potential rational zero until d equation equals zero.
then u divide synthetically
after u divide synthetically, u will end up with a linear equation
then u factorize and find your zeros...

Aaah, das mit der potenzregel hab ich verstanden. Das ist für Diese Funktionen gedacht^^.
Aber ich weiß halt nicht, wie man das mit dem Differenzenquotienten rechnet. so müssen wir es in der Schule rechnen.

Ja, aber mir ist der Rechenweg nicht klar.
PS: Und warum geht das auch ohne die Formel? Geht das immer??? Das verstehe ich noch nicht, wieso

Mathx:
(f(x+h) - f(x)) / h
geht natürlich auch, siehe:

Dachte, man braucht eine diese Formel dazu:
(f(x+h) - f(x)) / h
So rechne ich das immer.

1/x^2 = x^-2
x^-2 kann vergleichbar zu x^2 abgeleitet werden:
(x^-2)' = -2 * x^(-2-1) = -2 * x^-3 = -2/x^3
