Sketch the graph of f(x)= A. The domain is R. B. C. D. The x- and y-intercepts are both Since f(-x) = -f(x), fis ---Select--- and its graph is symmetric about the origin. f(x) = Since x² + 7 is never 0, there is no vertical asymptote. Since f(x) → ∞o as x → ∞o and f(x)→-coas x→∞o, there is no horizontal asymptote. But long division gives us the following. f(x) - = - X = = x² + 7 x³ +7 So the line y = = X- x² + 7 1 + x² + 7 as x ±0o is a slant asymptote.
