1. ## Fnctions

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]

Hey Anzamnia.

Can you show us your attempts?

Do you understand how to graph functions?

3. ## Re: Fnctions

My attempts were took by my teacher. Ive do something, but not confident in my tryings. Results will be known in next week. Just want to have fallback.
Ill try to rewrite my solves later.

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

5. ## Re: Fnctions

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