Sketch the graph of f(x)=x^2/x-2. Identify the domain, x-intercepts, y intercepts, symmetry, periodicity, asymptotes, increasing and decreasing intervals, local max/min, concavity, inflexion points.
whew. can you show us what you got? Maybe you solved it correctly. Or, what isn't clear?
I'm Sort of not understanding how to find symmetry, periodicity.
The xintercept and yintercept, you plug 0 into the y to find the y intercept? then 0 into x for the xvalue? or vice versa?
Increasing and decreasing are the derivative = to 0, if its negative its decreasing and if it is positive its increasing?
Inflection points I always have a hard time on.
