Hi, one more question. I am defining the max and mix value of a function, and I use the Lagrange method - I would need help forming the function pair in this kind of question (aka forming partial derivative for x1 and x2). Could you help with this? The function is f(x1,x2)=x1x2 and the condition is the latter function seen in the picture.

Could you help with this? The function is f(x1,x2)=x1x2 and the condition is the latter function seen in the picture. 

f(x1, x₂) = x1x2
suurin ja pienin arvo joukossa x² + 4x² = 8.
Transcribed Image Text:f(x1, x₂) = x1x2 suurin ja pienin arvo joukossa x² + 4x² = 8.
