Using Functions Involving e Notes 7.3 (Day 2) Using Functions Involving e
Natural Base Exponential Function: If a > 0 and r > 0, the function is an exponential growth function If a > 0 and r < 0, the function is an exponential decay function Example of Exponential Growth: Example of Exponential Decay:
Graphing exponential growth and decay with e. Step 1: Draw coordinate plane. Step 2: Place pencil on a value on the y axis. Step 3: Move left or right according to h. Step 4: Move up or down according to k. Step 5: Place your first point. Step 6: Label your asymptote. (k value) Step 7: Make a t-chart with a point to the right and left of your beginning point. Step 8: Graph and connect the points. ***The r value tells whether the function will be exponential growth or decay. (positive -> growth, negative -> decay)
