1. Which of the following functions represents exponential decay?
f(x) = 3^x
f(x) = (1/2)^x
f(x) = x^2
f(x) = 2x + 1
2. What is the y-intercept of the function y = 4 * 2^x?
(0, 2)
(0, 4)
(0, 8)
(0, 1)
3. In the exponential function f(x) = a * b^x, 'a' represents the and 'b' represents the .
4. If the growth factor 'b' in an exponential function is between 0 and 1, the function represents exponential .
5. Describe how the graph of y = 2^x + 3 differs from the graph of y = 2^x.
6. Graph the function y = 3^x on the coordinate plane below.
7. The domain of an exponential function is all real numbers.
True
False
8. An exponential function always has a horizontal asymptote.
True
False
9. A population of bacteria doubles every hour. If you start with 100 bacteria, write an exponential function to model the population (P) after 't' hours. Then, use your function to find the population after 3 hours.
