Exponential Equations variable is part of an exponent to solve an exponential equation previous courses algebraically manipulate using logarithms Math Studies using GDC, on “Y=” screen enter each side of the equation for two different functions using the “CALC” menu, choose “intersect” to find where the two functions cross (may have to adjust window settings) Example Copy Copy 18A, 18B, 18C, 18D 5/1/2019 8:24 PM

Exponential Functions Copy often used to model a population or determine compound interest a: “initial value”; when negative: reflection across horizontal asymptote b: b > 1 growth 0 < b < 1 decay c: horizontal shift d: y = d horizontal asymptote (vertical shift) to graph: determine and graph the asymptote find and plot the locator point (when x – c = 0) find and plot additional points 18A, 18B, 18C, 18D 5/1/2019 8:24 PM
