Use a calculator to graph the rational function in the window indicated. Use the graph to (a) give the x- and y-intercepts, (b) explain why there are no vertical asymptotes, (c) give the equation of the oblique asymptote, and (d) give the domain and range.f(x) = ; [-6, 6] by [-3, 3]
A. (a) x-intercepts: (-4, 0), (-1, 0), (1, 0); y-intercept: ;
(b) The denominator has no real zeros because the discriminant, -28, is negative.;
(c) y = - x -
;
(d) The domain and range are both (-?, ?).
B. (a) x-intercepts: (-8, 0), (-2, 0), (2, 0); y-intercept: ;
(b) The denominator has no real zeros because the discriminant, -28, is negative.;
(c) y = x +
