Question

y=x^3/x^2-3 Find the intervals on which the curve is concave upward?

Answer 1

Have you considered the 2nd Derivative? It's a little tedious. Break out your best algebra and get it done.

Answer 2

You have written, \(y=\dfrac{x^{3}}{x^{2}}−3\). Was this your intent? Notation matters!

Answer 3

Is this a calculus problem or an algebra problem concerned with Rational Functions?

Answer 4

my guess is this is a pre-calc question so you haven't learned derivatives yet.

so use graphing calculator and/or find vertical/slant asymptotes to examine graph and determine where its concave up
