    Hello. U r my only hope. Please help with that tasks:
    1. Full investigation and graphic
    A) y=x/(9-x) B) y=x^2*e^((x^2)/2)

    2. Min and max f(x)

    f(x)=(x^2)/2+8/x+8 on [-4; -1]

    Tnx for your time :3

    Hey Anzamnia.

    Can you show us your attempts?

    Do you understand how to graph functions?

    Have you tried plotting a few values of y for a given x and then draw a curve through it?

    You posted this under "differential geometry" but these problems are certainly not that advanced. What level of mathematics can you do? Algebra? PreCalculus" Calculus?
