The graph of a rational function f is shown below. Assume that all asymptotes and intercepts are shown and that the graph has no "holes".
Use the graph to complete the following.
(a) Find all x-intercepts and y-intercepts. Check all that apply.
x-intercept(s): 4 0 1 None
y-intercept(s): 1 4 0 None
(b) Write the equations for all vertical and horizontal asymptotes. Enter the equations using the "and" button as necessary. Select "None" as necessary.
Vertical asymptote(s):
Horizontal asymptote(s):
(c) Find the domain and range of f. Write each answer as an interval or union of intervals.
Domain:
Range:
