Question

f(x)=(x^3/3)-2x^2-5x+1Find all asymptotes, extrema, intercepts, and points of inflection.

Answer 1

I'm also supposed to identify concave up or concave down.

Answer 2

this is a polnomial function so theres no asymptotes

Answer 3

to get the y intercep, find f(0)=

Answer 4

to get the x intercept, solve f(x) =0

Answer 5

I got (-17/3, 1) as the y intercept

Answer 6

What do you mean f(x)=0?

Answer 7

Sorry, I mean (0,1) as the y intercept. I do not know how to find the x intercepts.

Answer 8

Okay, on the search for x-intercepts, I have gotten to this point... \[x(x^2-6x-15)=-3\]
