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) = 
; [-7, 7] by [-32, 32]
A. (a) x-intercepts: (-5, 0), (-3, 0), (5, 0); y-intercept: 
;
(b) The denominator has no real zeros because the discriminant, -68, is negative.;
(c) y = 2x + 5;
(d) The domain and range are both (-?, ?).
B. (a) x-intercepts: (-3, 0), (-5, 0), (3, 0); y-intercept: 
;
(b) The denominator has no real zeros because the discriminant, -47, is negative.;
(c) y = 2x + 11;
(d) The domain and range are both (-?, ?).
C. (a) x-intercepts: (-3, 0), (-5, 0), (3, 0); y-intercept:
