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 [-10, 10]

A. (a) x-intercepts: (-4, 0), , (4, 0); y-intercept: ;
(b) The denominator has no real zeros because the discriminant, -15, is negative.;
(c) y = 3x - 1;
(d) The domain and range are both (-?, ?).
B. (a) x-intercepts: (-4, 0), , (4, 0); y-intercept: ;
(b) The denominator has no real zeros because the discriminant, -17, is negative.;
(c) y = 3x - 1;
(d) The domain and range are both [0, ?).
C. (a) x-intercepts: (-2, 0), , (2, 0); y-intercept: ;
(b) The denominator has no real zeros because the discriminant, -17, is negative.;
(c) y = 3x + 7;
(d) The domain and range are both (-?, ?).
D. (a) x-intercepts: (-2, 0), , ; y-intercept: ;
(b) The denominator has no real zeros because the discriminant, -15, is negative.;
(c) y = 3x + 1;
(d) The domain and range are both [0, ?).
