Can someone tell me what this function's name is?

>>8724145
f''(x)

f(-1/12)

>>8724145
k(x+2)(x-1)(x-3)

assume f(x) = ax^4+bx^3+cx^2+dx+e
solve the linear system of equations
f(-2) = 0
f'(-0.8) = 0
f(1) = 0
f'(2.1) = 0
f(3) = 0
for a b c d and e

good job complicating things
>>8724175
is sufficient

>good job complicating things
it's as complicated as it needs to be
his polynomial can't have zero derivative at -.8 and 2.1 for k != 0

>>8724214
solve the zeros of the derivative of k(x+2)(x-1)(x-3) you noob

>>8724220
guess what retard, (2+-sqrt(19))/3 is neither -0.8 nor 2.1

>>8724225
what is rounding lol

>>8724189
>ax^4
wrong

>>8724145
The second derivative is a cubic so f(x) is a quintic

>>8724145
this function is called 'fuck off undergrad'

looks like cosine, i think it is cos x ya

THIS !

This M8, is a example for an cubic function.

f(x) = ax^3+bx^2+cx+d

Let´s take a look at the Stats of our function.
You´ve got 3 intersections on the X axis and a high point at x = -0.8 and a low point at x = 2.1.

f (-2) = 0
f ( 1) = 0
f ( 3) = 0
f´ (-0,8) = 0
f´ (2,1) = 0

Next Step:

f (x) = ax^3+bx^2+cx+d
f´ (x) = 3ax^2+2bx+c


Now you can set up and solve the equations.

By integration it can be seen that the parent function is 5.Grades.

this function isn't arthur. i know arthur. this better not be arthur.

>>8728322
can you show, that it can't be a fifth order polynomial?

>>8724145
dirac delta function

>Can someone tell me what this function's name is?
The real answer to this question is "no."
There are an infinite number of functions that would have that exact plot, so no one can give you one specific name.
