I translated this with gpt from german to english.. if you dont understand the translation i am happy to help with that
The so-called total ozone is a measure of the thickness of the ozone layer and is given in so-called Dobson Units (DU). The measurement data recorded by a weather balloon can be modeled by a quadratic function
π
f. Here,
π
f associates the total ozone density
π
(
β
)
f(h) with the altitude
β
h (with
β
h in km, and
π
(
β
)
f(h) in DU/km).
The highest value of
36

DU/km
36DU/km is measured at an altitude of

22km. At an altitude of
37

37km, the measured value is

Note:

The following conditions can be derived from the given information:

f(37)=1
π

f(22)=36

(22)=0, since the highest value is measured at an altitude of

22km, which also represents the maximum point.
Form the first derivative of the function
π

f(h). Then set up equations and solve the system of equations to find values for
π
a,
π
b, and
π
c.

This can be done manually or with the help of GeoGebra:
Enter the function
π
(

)
f(h) in the input field.
Choose Integral(<Function>,<Start Value>,<End Value>), where you set the function to
π
(
β
)
f(h), the start value to
7
7, and the end value to
37
37.
Since

Determine
