3. Functions f(x) and g(x) have the following proprieties: lim f(x) =-4 lim g(x) = -co (a) (2 points) Using the given information, which of the following claims about f(x) can be made? O f(x) has a vertical asymptote at T = -4. O f(x) has a horizontal asymptote at y = -4. O As a approaches co, f(x) approaches co. Of(x) is not differentiable at a - -4. (b) (2 points) Using the given information, which of the following claims about g(r ) can be made? O g(r) has a vertical asymptote at O g(x) has a horizontal asymptote at y- O As r approaches co, g(r) approaches -Do O g(x) is continuous at z = 6
