Figure 7-6d shows the logistic function Figure 7-6d a. Explain algebraically why the graph has a horizontal asymptote at y = 3. b. Read the point of inflection from the graph. Find the x-coordinate algebraically. c. For what values of x is the graph concave up? Concave down? d. Transform the equation so that there is only one exponential term. Confirm by graphing that the resulting equation is equivalent to f(x) as given.
