Exponential Functions are functions which can be represented by graphs similar to the graph on the right

Exponential Functions are functions which can be represented by graphs similar to the graph on the right. All base exponential functions are similar because they all go through the point (0,1), regardless of the size of their base number. Exponential Functions are written in the form: y = ab x

  1. Exponential Functions are functions which can be represented by graphs similar to the graph on the right

  2. All base exponential functions are similar because they all go through the point (0,1), regardless of the size of their base number Exponential Functions are written in the form: y = abx a= constant b = base x = variable

  3. When working with exponential equations, the Laws of Exponentsstill hold true When solving exponential equations, it is important to have both sides of the equation set to the same base

  4. Yellow = 4xGreen = ex Black = 3x Red = 2x

  5. As you could see in the graph, the larger the base, the faster the function increased If we place a negative sign in front of the x, the graphs will be reflected(flipped) across the y-axis

  6. Yellow = 4-xGreen = e-x Black = 3-x Red = 2-x

  7. By using Microsoft Excel, we can make a table of values and a graph of the data y = ex

  8. We can also use Maple 7 to plot exponential graphs > plot (exp(x),x=-5..5);

  9. The previous pages show what exponential growth looks like as a curve, but what happens in real life. You start with one item which replicates continuously.
