7 For s (x) 2 4 4x+ 4 (a) Identify the horizontal asymptotes (if any). (b) If the graph of the function has any horizontal asymptote, determine the point (if any) where the graph crosses the horizontal asymptote(s). Write numbers as integers or simplified fractions. If there is more than one answer, use the "and" button. The graph has no horizontal asymptotes. 0-0 (0,0) O The graph has at least one horizontal asymptote. and None Equation(s) of the horizontal asymptote(s): X 5 Crossover point(s)
