(a) The exponential functions in Figure 1.73 have b, d, q positive. Which of the constants a, c, and p must be positive? 

(b) Which of the constants a, b, c, d, p, and q must be between 0 and 1? 

(c) Which two of the constants a, b, c, d, p, and q must be equal? 

(d) What information about the constants a and b does the point (1, 1) provide?
