1. You Decide Todd says that y = 2 is an exponential function, Juan disagrees. Who is correct? Explain. 2. Describe the domains and ranges of functions of the form y = a . b when: a. a = 1, b > 0. ba > 1, b > 0. c. a0 3. Compare the graphs of the y = 2 ", y = (2) and y = (0.5) ". 4. Explain how you could use a calculator to determine which of the following values is the best approximation for the value of x in the equation 3 - 2. 3", Give the best approximation among the choices below. a. 1.2 b. 1.3 c. 1.4 d. 1.5 5. Name the y-intercepts for the graph of y = b", where b is any real number. 6. Compare and contrast the graphs of y = b" when b > 1 and when 0
