Let f(x) = sin^-1 (1-x^2/1+x^2) . Graph the function f by first finding the following: (a) the domain of f, (b) x and y intercepts (if any), (c) asymptotes (d) end behavior (limits at infinity) (e) intervals where the function is increasing or decreasing, (f) local extrema, (g) intervals where the function is concave up or concave down, (h) inflection points.
