Coordinate Algebra • UNIT QUESTION: How can we use real-world situations to construct and compare linear and exponential models and solve problems? • Standards: MCC9-12.A.REI.10, 11, F.IF.1-7, 9, F.BF.1-3, F.LE.1-3, 5 • Today’s Question: • How can I tell if an exponential function is a growth or decay curve? • Standard: MCC9-12.F.LE.1c
Example 1 y = 2x Domain: Range: Asymptote: Increase/Decrease
Example 2 f(x) = 2x – 1 Domain: Range: Asymptote: Increase/Decrease
Example 3 f(x) = 2x – 1 + 3 Domain: Range: Asymptote: Increase/Decrease
